+# GitHub Copilot Instructions for Palmr
+
+This file contains instructions for GitHub Copilot to help contributors work effectively with the Palmr codebase.
+
+## Project Overview
+
+Palmr is a flexible and open-source alternative to file transfer services like WeTransfer and SendGB. It's built with:
+
+- **Backend**: Fastify (Node.js) with TypeScript, SQLite database, and filesystem/S3 storage
+- **Frontend**: Next.js 15 + React + TypeScript + Shadcn/ui
+- **Documentation**: Next.js + Fumadocs + MDX
+- **Package Manager**: pnpm (v10.6.0)
+- **Monorepo Structure**: Three main apps (web, server, docs) in the `apps/` directory
+
+## Architecture and Structure
+
+### Monorepo Layout
+
+```
+apps/
+├── docs/       # Documentation site (Next.js + Fumadocs)
+├── server/     # Backend API (Fastify + TypeScript)
+└── web/        # Frontend application (Next.js 15)
+```
+
+### Key Technologies
+
+- **TypeScript**: Primary language for all applications
+- **Database**: Prisma ORM with SQLite (optional S3-compatible storage)
+- **Authentication**: Multiple OAuth providers (Google, GitHub, Discord, etc.)
+- **Internationalization**: Multi-language support with translation scripts
+- **Validation**: Husky pre-push hooks for linting and type checking
+
+## Development Workflow
+
+### Base Branch
+
+Always create new branches from and submit PRs to the `next` branch, not `main`.
+
+### Commit Convention
+
+Use Conventional Commits format for all commits:
+
+```
+<type>(<scope>): <description>
+
+Types:
+- feat: New feature
+- fix: Bug fix
+- docs: Documentation changes
+- test: Adding or updating tests
+- refactor: Code refactoring
+- style: Code formatting
+- chore: Maintenance tasks
+```
+
+Examples:
+
+- `feat(web): add user authentication system`
+- `fix(api): resolve null pointer exception in user service`
+- `docs: update installation instructions in README`
+- `test(server): add unit tests for user validation`
+
+### Code Quality Standards
+
+1. **Linting**: All apps use ESLint. Run `pnpm lint` before committing
+2. **Formatting**: Use Prettier for code formatting. Run `pnpm format`
+3. **Type Checking**: Run `pnpm type-check` to validate TypeScript
+4. **Validation**: Run `pnpm validate` to run both linting and type checking
+5. **Pre-push Hook**: Automatically validates all apps before pushing
+
+### Testing Changes
+
+- Test incrementally during development
+- Run validation locally before pushing: `pnpm validate` in each app directory
+- Keep changes focused on a single issue or feature
+- Review your work before committing
+
+## Application-Specific Guidelines
+
+### Web App (`apps/web/`)
+
+- Framework: Next.js 15 with App Router
+- Port: 3000 (development)
+- Scripts:
+  - `pnpm dev`: Start development server
+  - `pnpm build`: Build for production
+  - `pnpm validate`: Run linting and type checking
+- Translations: Use Python scripts in `scripts/` directory
+  - `pnpm translations:check`: Check translation status
+  - `pnpm translations:sync`: Synchronize translations
+
+### Server App (`apps/server/`)
+
+- Framework: Fastify with TypeScript
+- Port: 3333 (default)
+- Scripts:
+  - `pnpm dev`: Start development server with watch mode
+  - `pnpm build`: Build TypeScript to JavaScript
+  - `pnpm validate`: Run linting and type checking
+  - `pnpm db:seed`: Seed database
+- Database: Prisma ORM with SQLite
+
+### Docs App (`apps/docs/`)
+
+- Framework: Next.js with Fumadocs
+- Port: 3001 (development)
+- Content: MDX files in `content/docs/`
+- Scripts:
+  - `pnpm dev`: Start development server
+  - `pnpm build`: Build documentation site
+  - `pnpm validate`: Run linting and type checking
+
+## Code Style and Best Practices
+
+### General Guidelines
+
+1. **Follow Style Guidelines**: Ensure code adheres to ESLint and Prettier configurations
+2. **TypeScript First**: Always use TypeScript, avoid `any` types when possible
+3. **Component Organization**: Keep components focused and single-purpose
+4. **Error Handling**: Implement proper error handling and logging
+5. **Comments**: Add comments only when necessary to explain complex logic
+6. **Imports**: Use absolute imports where configured, keep imports organized
+
+### API Development (Server)
+
+- Use Fastify's schema validation for all routes
+- Follow REST principles for endpoint design
+- Implement proper authentication and authorization
+- Handle errors gracefully with appropriate status codes
+- Document API endpoints in the docs app
+
+### Frontend Development (Web)
+
+- Use React Server Components where appropriate
+- Implement proper loading and error states
+- Follow accessibility best practices (WCAG guidelines)
+- Optimize performance (lazy loading, code splitting)
+- Use Shadcn/ui components for consistent UI
+
+### Documentation
+
+- Write clear, concise documentation
+- Include code examples where helpful
+- Update documentation when changing functionality
+- Use MDX features for interactive documentation
+- Follow the existing documentation structure
+
+## Translation and Internationalization
+
+- All user-facing strings should be translatable
+- Use the Next.js internationalization system
+- Translation files are in `apps/web/messages/`
+- Reference file: `en-US.json`
+- Run `pnpm translations:check` to verify translations
+- Mark untranslated strings with `[TO_TRANSLATE]` prefix
+
+## Common Patterns
+
+### Authentication Providers
+
+- Provider configurations in `apps/server/src/modules/auth-providers/providers.config.ts`
+- Support for OAuth2 and OIDC protocols
+- Field mappings for user data normalization
+- Special handling for providers like GitHub that require additional API calls
+
+### File Storage
+
+- Default: Filesystem storage
+- Optional: S3-compatible object storage
+- File metadata stored in SQLite database
+
+### Environment Variables
+
+- Configure via `.env` files (not committed to repository)
+- Required variables documented in README or docs
+- Use environment-specific configurations
+
+## Contributing Guidelines
+
+### Pull Request Process
+
+1. Fork the repository
+2. Create a branch from `next`: `git checkout -b feature/your-feature upstream/next`
+3. Make focused changes addressing a single issue/feature
+4. Write or update tests as needed
+5. Update documentation to reflect changes
+6. Ensure all validations pass: `pnpm validate` in each app
+7. Commit using Conventional Commits
+8. Push to your fork
+9. Create Pull Request targeting the `next` branch
+
+### Code Review
+
+- Be responsive to feedback
+- Keep discussions constructive and professional
+- Make requested changes promptly
+- Ask questions if requirements are unclear
+
+### What to Avoid
+
+- Don't mix unrelated changes in a single PR
+- Don't skip linting or type checking
+- Don't commit directly to `main` or `next` branches
+- Don't add unnecessary dependencies
+- Don't ignore existing code style and patterns
+- Don't remove or modify tests without good reason
+
+## Helpful Commands
+
+### Root Level

-title: Quick Start (Docker)
-icon: "Rocket"
----
-
-Welcome to the fastest way to deploy <span className="font-bold">Palmr.</span> - your secure, self-hosted file sharing solution. This guide will have you up and running in minutes, whether you're new to self-hosting or an experienced developer.
-
-Palmr. offers flexible deployment options to match your infrastructure needs. This guide focuses on Docker deployment with our recommended filesystem storage, perfect for most use cases.
-
-## Prerequisites
-
-Ensure you have the following installed on your system:
-
-- **Docker** - Container runtime ([installation guide](https://docs.docker.com/get-docker/))
-- **Docker Compose** - Multi-container orchestration ([installation guide](https://docs.docker.com/compose/install/))
-
-> **Platform Support**: Palmr. is developed on macOS and extensively tested on Linux servers. While we haven't formally tested other platforms, Docker's cross-platform nature should ensure compatibility. Report any issues on our [GitHub repository](https://github.com/kyantech/Palmr/issues).
-
-## Storage Options
-
-Palmr. supports two storage approaches for persistent data:
-
-### Named Volumes (Recommended)
-
-**Best for**: Production environments, automated deployments
-
-- ✅ **Managed by Docker**: No permission issues or manual path management
-- ✅ **Optimized Performance**: Docker-native storage optimization
-- ✅ **Cross-platform**: Consistent behavior across operating systems
-- ✅ **Simplified Backups**: Docker volume commands for backup/restore
-
-### Bind Mounts
-
-**Best for**: Development, direct file access requirements
-
-- ✅ **Direct Access**: Files stored in local directory you specify
-- ✅ **Transparent Storage**: Direct filesystem access from host
-- ✅ **Custom Backup**: Use existing file system backup solutions
-- ⚠️ **Permission Considerations**: **Common Issue** - Requires UID/GID configuration (see troubleshooting below)
-
----
-
-## Option 1: Named Volumes (Recommended)
-
-Named volumes provide the best performance and are managed entirely by Docker.
-
-### Configuration
-
-Use the provided `docker-compose.yaml` for named volumes:
-
-```yaml
-services:
-  palmr:
-    image: kyantech/palmr:latest
-    container_name: palmr
-    environment:
-      - ENABLE_S3=false
-      - ENCRYPTION_KEY=change-this-key-in-production-min-32-chars # CHANGE THIS KEY FOR SECURITY
-      # - SECURE_SITE=false # Set to true if you are using a reverse proxy
-    ports:
-      - "5487:5487" # Web interface
-      - "3333:3333" # API port (OPTIONAL EXPOSED - ONLY IF YOU WANT TO ACCESS THE API DIRECTLY)
-    volumes:
-      - palmr_data:/app/server # Named volume for the application data
-    restart: unless-stopped # Restart the container unless it is stopped
-
-volumes:
-  palmr_data:
-```
-
-> **Note:** If you haveing problem with uploading files, try to change the `PALMR_UID` and `PALMR_GID` to the UID and GID of the user running the container. You can find the UID and GID of the user running the container with the command `id -u` and `id -g`. in Linux systems the default user is `1000` and the default group is `1000`. For test you can add the environment variables below to the `docker-compose.yaml` file and restart the container.
-
-```yaml
-environment:
-  - PALMR_UID=1000 # UID for the container processes (default is 1001)
-  - PALMR_GID=1000 # GID for the container processes (default is 1001)
-```
-
-> **Note:** For more information about UID and GID, see our [UID/GID Configuration](/docs/3.1-beta/uid-gid-configuration) guide.
-
-### Deployment
-
-```bash
-docker-compose up -d
-```
-
----
-
-## Option 2: Bind Mounts
-
-Bind mounts store data in a local directory, providing direct file system access.
-
-### Configuration
-
-To use bind mounts, **replace the content** of your `docker-compose.yaml` with the following configuration (you can also reference `docker-compose-bind-mount-example.yaml` as a template):
-
-```yaml
-services:
-  palmr:
-    image: kyantech/palmr:latest
-    container_name: palmr
-    environment:
-      - ENABLE_S3=false
-      - ENCRYPTION_KEY=change-this-key-in-production-min-32-chars # CHANGE THIS KEY FOR SECURITY
-      # - SECURE_SITE=false # Set to true if you are using a reverse proxy
-      - PALMR_UID=1000 # UID for the container processes (default is 1001)
-      - PALMR_GID=1000 # GID for the container processes (default is 1001)
-    ports:
-      - "5487:5487" # Web port
-      - "3333:3333" # API port (OPTIONAL EXPOSED - ONLY IF YOU WANT TO ACCESS THE API DIRECTLY)
-    volumes:
-      # Bind mount for persistent data (uploads, database, temp files)
-      - ./data:/app/server # Local directory for the application data
-    restart: unless-stopped # Restart the container unless it is stopped
-```
-
-### Deployment
-
-```bash
-docker-compose up -d
-```
-
-> **Permission Configuration**: If you encounter permission issues with bind mounts (common on NAS systems), see our [UID/GID Configuration](/docs/3.1-beta/uid-gid-configuration) guide for automatic permission handling.
-
----
-
-## Environment Variables
-
-Configure Palmr. behavior through environment variables:
-
-| Variable         | Default | Description                                             |
-| ---------------- | ------- | ------------------------------------------------------- |
-| `ENABLE_S3`      | `false` | Enable S3-compatible storage                            |
-| `ENCRYPTION_KEY` | -       | **Required**: Minimum 32 characters for file encryption |
-| `SECURE_SITE`    | `false` | Enable secure cookies for HTTPS/reverse proxy setups    |
-
-> **⚠️ Security Warning**: Always change the `ENCRYPTION_KEY` in production. This key encrypts your files - losing it makes files permanently inaccessible.
-
-> **🔗 Reverse Proxy**: If deploying behind a reverse proxy (Traefik, Nginx, etc.), set `SECURE_SITE=true` and review our [Reverse Proxy Configuration](/docs/3.1-beta/reverse-proxy-configuration) guide for proper setup.
-
-### Generate Secure Encryption Keys
-
-Need a strong key for `ENCRYPTION_KEY`? Use our built-in generator to create cryptographically secure keys:
-
-<KeyGenerator />
-
----
-
-## Accessing Palmr.
-
-Once deployed, access Palmr. through your web browser:
-
-- **Local**: `http://localhost:5487`
-- **Server**: `http://YOUR_SERVER_IP:5487`
-
-### API Access (Optional)
-
-If you exposed port 3333 in your configuration, you can also access:
-
-- **API Documentation**: `http://localhost:3333/docs` (local) or `http://YOUR_SERVER_IP:3333/docs` (server)
-- **API Endpoints**: Available at `http://localhost:3333` (local) or `http://YOUR_SERVER_IP:3333` (server)
-
-> **📚 Learn More**: For complete API documentation, authentication, and integration examples, see our [API Reference](/docs/3.1-beta/api) guide.
-
-> **💡 Production Tip**: For production deployments, configure HTTPS with a valid SSL certificate for enhanced security.
-
----
-

+#### Performance Considerations with Encryption
+
+By default, filesystem storage operates without encryption for optimal performance, providing fast uploads and downloads with minimal CPU overhead. This approach is ideal for most use cases where performance is prioritized.
+
+If you need to protect sensitive files at rest, you can enable encryption by setting `DISABLE_FILESYSTEM_ENCRYPTION=false` and providing an `ENCRYPTION_KEY` in your configuration. When enabled, Palmr uses AES-256-CBC encryption, which adds CPU overhead during uploads (encryption) and downloads (decryption), particularly for large files or in resource-constrained environments like containers or low-end VMs.
+
+For optimal performance with encryption enabled, ensure your hardware supports AES-NI acceleration (check with `cat /proc/cpuinfo | grep aes` on Linux).
+
+As an alternative, consider using S3-compatible object storage (e.g., AWS S3 or MinIO), which can offload file storage from the local filesystem and potentially reduce local CPU overhead for encryption/decryption. See [S3 Providers](/docs/3.2-beta/s3-providers) for setup instructions.

 ### Fastify + Zod + TypeScript
 
 The backend of Palmr. is powered by **Fastify**, **Zod**, and **TypeScript**, creating a robust and type-safe API layer. Fastify is a super-fast Node.js web framework optimized for performance and low overhead, designed to handle lots of concurrent requests with minimal resource usage. Zod provides runtime type validation and schema definition, ensuring all incoming data is properly validated before reaching business logic. TypeScript adds compile-time type safety throughout the entire backend codebase. This combination creates a highly reliable and maintainable backend that prevents bugs and security issues while maintaining excellent performance.

+title: Cleanup Orphan Files
+icon: Trash2
+---
+
+This guide provides detailed instructions on how to identify and remove orphan file records from your Palmr database. Orphan files are database entries that reference files that no longer exist in the storage system, typically resulting from failed uploads or interrupted transfers.
+
+## When and why to use this tool
+
+The orphan file cleanup script is designed to maintain database integrity by removing stale file records. Consider using this tool if:
+
+- Users are experiencing "File not found" errors when attempting to download files that appear in the UI
+- You've identified failed uploads that left incomplete database records
+- You're performing routine database maintenance
+- You've migrated storage systems and need to verify file consistency
+- You need to free up quota space occupied by phantom file records
+
+> **Note:** This script only removes **database records** for files that don't exist in storage. It does not delete physical files. Files that exist in storage will remain untouched.
+
+## How the cleanup works
+
+Palmr provides a maintenance script that scans all file records in the database and verifies their existence in the storage system (either filesystem or S3). The script operates in two modes:
+
+- **Dry-run mode (default):** Identifies orphan files and displays what would be deleted without making any changes
+- **Confirmation mode:** Actually removes the orphan database records after explicit confirmation
+
+The script maintains safety by:
+- Checking file existence before marking as orphan
+- Providing detailed statistics and file listings
+- Requiring explicit `--confirm` flag to delete records
+- Working with both filesystem and S3 storage providers
+- Preserving all files that exist in storage
+
+## Understanding orphan files
+
+### What are orphan files?
+
+Orphan files occur when:
+
+1. **Failed chunked uploads:** A large file upload starts, creates a database record, but the upload fails before completion
+2. **Interrupted transfers:** Network issues or server restarts interrupt file transfers mid-process
+3. **Manual deletions:** Files are manually deleted from storage without removing the database record
+4. **Storage migrations:** Files are moved or lost during storage system changes
+
+### Why they cause problems
+
+When orphan records exist in the database:
+- Users see files in the UI that cannot be downloaded
+- Download attempts result in "ENOENT: no such file or directory" errors
+- Storage quota calculations become inaccurate
+- The system returns 500 errors instead of proper 404 responses (in older versions)
+
+### Renamed files with suffixes
+
+Files with duplicate names are automatically renamed with suffixes (e.g., `file (1).png`, `file (2).png`). Sometimes the upload fails after the database record is created but before the physical file is saved, creating an orphan record with a suffix.
+
+**Example:**
+```
+Database record: photo (1).png → objectName: user123/1758805195682-Rjn9at692HdR.png
+Physical file: Does not exist ❌
+```
+
+## Step-by-step instructions
+
+### 1. Access the server environment
+
+**For Docker installations:**
+
+```bash
+docker exec -it <container_name> /bin/sh
+cd /app/palmr-app
+```
+
+**For bare-metal installations:**
+
+```bash
+cd /path/to/palmr/apps/server
+```
+
+### 2. Run the cleanup script in dry-run mode
+
+First, run the script without the `--confirm` flag to see what would be deleted:
+
+```bash
+pnpm cleanup:orphan-files
+```
+
+This will:
+- Scan all file records in the database
+- Check if each file exists in storage
+- Display a summary of orphan files
+- Show what would be deleted (without actually deleting)
+
+### 3. Review the output
+
+The script will provide detailed information about orphan files:
+
+```text

+
+⚠️  Dry run mode. To actually delete orphan records, run with --confirm flag:
+   pnpm cleanup:orphan-files:confirm
+```
+
+### 4. Confirm and execute the cleanup
+
+If you're satisfied with the results and want to proceed with the deletion:
+
+```bash
+pnpm cleanup:orphan-files:confirm
+```
+
+This will remove the orphan database records and display a confirmation:

+
+### No orphan files found
+
+```text
+📊 Summary:
+  Total files in DB: 10
+  ✅ Files with storage: 10
+  ❌ Orphan files: 0
+
+✨ No orphan files found!
+```
+
+**This is good!** It means your database is in sync with your storage system.
+
+### Script cannot connect to database
+
+If you see database connection errors:
+
+1. Verify the database file exists:
+   ```bash
+   ls -la prisma/palmr.db
+   ```
+
+2. Check database permissions:
+   ```bash
+   chmod 644 prisma/palmr.db
+   ```
+
+3. Ensure you're in the correct directory:
+   ```bash
+   pwd  # Should show .../palmr/apps/server
+   ```
+
+### Storage provider errors
+
+For **S3 storage:**
+- Verify your S3 credentials are configured correctly
+- Check that the bucket is accessible
+- Ensure network connectivity to S3
+
+For **Filesystem storage:**
+- Verify the uploads directory exists and is readable
+- Check file system permissions
+- Ensure sufficient disk space
+
+### Script fails to delete records
+
+If deletion fails for specific files:
+- Check database locks (close other connections)
+- Verify you have write permissions to the database
+- Review the error message for specific details
+
+## Understanding the output
+
+### File statistics
+
+The script provides several key metrics:
+
+- **Total files in DB:** All file records in your database
+- **Files with storage:** Records where the physical file exists
+- **Orphan files:** Records where the physical file is missing
+
+### File information
+
+For each orphan file, you'll see:
+
+- **Name:** Display name in the UI
+- **Size:** File size as recorded in the database
+- **Object name:** Internal storage path
+
+Example: `photo(1).png (0.76 MB) - user123/1758805195682-Rjn9at692HdR.png`
+
+## Prevention and best practices
+
+### Prevent orphan files from occurring
+
+1. **Monitor upload failures:** Check server logs for upload errors
+2. **Stable network:** Ensure reliable network connectivity for large uploads
+3. **Adequate resources:** Provide sufficient disk space and memory
+4. **Regular maintenance:** Run this script periodically as part of maintenance
+
+### When to run cleanup
+
+Consider running the cleanup script:
+
+- **Monthly:** As part of routine database maintenance
+- **After incidents:** Following server crashes or storage issues
+- **Before migrations:** Before moving to new storage systems
+- **When users report errors:** If download failures are reported
+
+### Safe cleanup practices
+
+1. **Always run dry-run first:** Review what will be deleted before confirming
+2. **Backup your database:** Create a backup before running with `--confirm`
+3. **Check during low usage:** Run during off-peak hours to minimize disruption
+4. **Document the cleanup:** Keep records of when and why cleanup was performed
+5. **Verify after cleanup:** Check that file counts match expectations
+
+## Technical details
+
+### How files are stored
+
+When files are uploaded to Palmr:
+
+1. Frontend generates a safe object name using random identifiers
+2. Backend creates the final `objectName` as: `${userId}/${timestamp}-${randomId}.${extension}`
+3. If a duplicate name exists, the **display name** gets a suffix, but `objectName` remains unique
+4. Physical file is stored using `objectName`, display name is stored separately in database
+
+### Storage providers
+
+The script works with both storage providers:
+
+- **FilesystemStorageProvider:** Uses `fs.promises.access()` to check file existence
+- **S3StorageProvider:** Uses `HeadObjectCommand` to verify objects in S3 bucket
+
+### Database schema
+
+Files table structure:
+```typescript
+{
+  name: string           // Display name (can have suffixes like "file (1).png")
+  objectName: string     // Physical storage path (always unique)
+  size: bigint          // File size in bytes
+  extension: string     // File extension
+  userId: string        // Owner of the file
+  folderId: string?     // Parent folder (null for root)
+}
+```
+
+## Related improvements
+
+### Download validation (v3.2.3-beta+)
+
+Starting from version 3.2.3-beta, Palmr includes enhanced download validation:
+
+- Files are checked for existence **before** attempting download
+- Returns proper 404 error if file is missing (instead of 500)
+- Provides helpful error message to users
+
+This prevents errors when trying to download orphan files that haven't been cleaned up yet.
+
+## Security considerations
+
+- **Read-only by default:** Dry-run mode is safe and doesn't modify data
+- **Explicit confirmation:** Requires `--confirm` flag to delete records
+- **No file deletion:** Only removes database records, never deletes physical files
+- **Audit trail:** All actions are logged to console
+- **Permission-based:** Only users with server access can run the script
+
+> **Important:** This script does not delete physical files from storage. It only removes database records for files that don't exist. This is intentional to prevent accidental data loss.
+
+## FAQ
+
+**Q: Will this delete my files?**  
+A: No. The script only removes database records for files that are already missing from storage. Physical files are never deleted.
+
+**Q: Can I undo the cleanup?**  
+A: No. Once orphan records are deleted, they cannot be recovered. Always run dry-run mode first and backup your database.
+
+**Q: Why do orphan files have suffixes like (1), (2)?**  
+A: When duplicate files are uploaded, Palmr renames them with suffixes. If the upload fails after creating the database record, an orphan with a suffix remains.
+
+**Q: How often should I run this script?**  
+A: Monthly maintenance is usually sufficient. Run more frequently if you experience many upload failures.
+
+**Q: Does this work with S3 storage?**  
+A: Yes! The script automatically detects your storage provider (filesystem or S3) and works with both.
+
+**Q: What if I have thousands of orphan files?**  
+A: The script handles large numbers efficiently. Consider running during off-peak hours for very large cleanups.
+
+**Q: Can this fix "File not found" errors?**  
+A: Yes, if the errors are caused by orphan database records. The script removes those records, preventing future errors.

+Palmr implements an intelligent memory management system that prevents crashes during large file downloads (3GB+ by default), maintaining unlimited download capacity through adaptive resource control and an automatic queue system.
+

+
+```typescript
+const totalMemoryGB = require("os").totalmem() / 1024 ** 3;
+```
+

+
+## Download Queue System
+
+### How It Works
+
+The memory management system only activates for files larger than the configured minimum size (3GB by default). Smaller files bypass the queue system entirely and download immediately without memory management.
+
+When a user requests a download for a large file but all slots are occupied, the system automatically queues the download instead of returning a 429 error. The queue processes downloads in FIFO order (first in, first out).
+
+### Practical Example
+
+Consider a system with 8GB RAM (5 concurrent downloads, queue of 25, 3GB minimum) where users want to download files of various sizes:
+
+```bash
+# Small files (< 3GB): Bypass queue entirely
+[DOWNLOAD MANAGER] File document.pdf (0.05GB) below threshold (3.0GB), bypassing queue
+
+# Large files 1-5: Start immediately
+[DOWNLOAD MANAGER] Immediate start: 1734567890-abc123def
+[DOWNLOAD MANAGER] Starting video1.mp4 (5.2GB)
+
+# Large files 6-10: Automatically queued
+[DOWNLOAD MANAGER] Queued: 1734567891-def456ghi (Position: 1/25)
+[DOWNLOAD MANAGER] Queued file: video2.mp4 (8.1GB)
+
+# When download 1 finishes: download 6 starts automatically
+[DOWNLOAD MANAGER] Processing queue: 1734567891-def456ghi (4 remaining)
+[DOWNLOAD MANAGER] Starting queued file: video2.mp4 (8.1GB)
+```
+
+### System Benefits
+
+**User Experience**
+
+- Users don't receive errors, they simply wait in queue
+- Downloads start automatically when slots become available
+- Transparent operation without client changes
+- Fair processing order with FIFO queue
+
+**Technical Features**
+
+- Limited buffers (64KB per stream) for controlled memory usage
+- Automatic backpressure control with pipeline streams
+- Adaptive memory throttling based on usage patterns
+- Forced garbage collection after large downloads
+- Smart timeout handling (30 minutes for queued downloads)
+- Automatic cleanup of orphaned downloads every 30 seconds

+## Troubleshooting
+
+### Common Issues
+
+**Downloads failing with "Download queue is full"**
+
+_Cause:_ Too many simultaneous downloads with a full queue
+
+_Solutions:_
+
+- Wait for some downloads to finish
+- Check for orphaned downloads in queue
+- Consider increasing container resources
+- Use API to clear queue if necessary
+
+**Downloads stay too long in queue**
+
+_Cause:_ Active downloads are slow or stuck
+
+_Solutions:_
+
+- Check logs for orphaned downloads
+- Use API to cancel specific downloads
+- Check client network connections
+- Monitor memory throttling
+
+**Very slow downloads**
+
+_Cause:_ Active throttling due to high memory usage
+
+_Solutions:_
+
+- Check other processes consuming memory
+- Consider increasing container resources
+- Monitor throttling logs
+- Check number of simultaneous downloads

+##### Upload Configuration
+
+Palmr. supports configurable chunked uploading for large files. You can customize the chunk size by setting the following environment variable in your `.env` file:
+
+```bash
+NEXT_PUBLIC_UPLOAD_CHUNK_SIZE_MB=100
+```
+
+**How it works:**
+
+- If `NEXT_PUBLIC_UPLOAD_CHUNK_SIZE_MB` is set, Palmr. will use this value (in megabytes) as the chunk size for all file uploads that exceed this threshold.
+- If not set or left empty, Palmr. automatically calculates optimal chunk sizes based on file size:
+  - Files ≤ 100MB: uploaded without chunking
+  - Files > 100MB and ≤ 1GB: 75MB chunks
+  - Files > 1GB: 150MB chunks
+
+**When to configure:**
+
+- **Default (not set):** Recommended for most use cases. Palmr. will intelligently determine the best chunk size.
+- **Custom value:** Set this if you have specific network conditions or want to optimize for your infrastructure (e.g., slower connections may benefit from smaller chunks like 50MB, while fast networks can handle larger chunks like 200MB, or the upload size per payload may be limited by a proxy like Cloudflare)

+### Custom Installation Paths and Symlinks
+
+If you're using a custom installation setup with symlinks (for example, `/opt/palmr_data/uploads -> /mnt/data/uploads`), you might encounter issues with disk space detection. Palmr. includes a `CUSTOM_PATH` environment variable to handle these scenarios:
+
+```bash
+# In your .env file (apps/server/.env)
+CUSTOM_PATH=/opt/palmr_data

+Welcome to the fastest way to deploy <span className="font-bold">Palmr.</span> - your secure, self-hosted file sharing solution. This guide will have you up and running in minutes, whether you're new to self-hosting or an experienced developer.
+
+Palmr. offers flexible deployment options to match your infrastructure needs. This guide focuses on Docker deployment with our recommended filesystem storage, perfect for most use cases.
+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+- **Docker** - Container runtime ([installation guide](https://docs.docker.com/get-docker/))
+- **Docker Compose** - Multi-container orchestration ([installation guide](https://docs.docker.com/compose/install/))
+- **2GB+ available disk space** for the application and your files
+- **Port 5487** available for the web interface
+- **Port 3333** available for API access (optional)
+
+<Callout>
+  **Platform Support**: Palmr. is developed on macOS and extensively tested on Linux servers. While we haven't formally
+  tested other platforms, Docker's cross-platform nature should ensure compatibility. Report any issues on our [GitHub
+  repository](https://github.com/kyantech/Palmr/issues).
+</Callout>
+
+## Storage Options
+
+Palmr. supports two storage approaches for persistent data:
+
+- **Named Volumes (Recommended)** - Docker-managed storage with optimal performance and no permission issues
+- **Bind Mounts** - Direct host filesystem access, ideal for development and direct file management
+
+## Deployment Options
+
+Choose your storage method based on your needs:
+
+<Tabs items={['Named Volumes (Recommended)', 'Bind Mounts']}>
+  <Tab value="Named Volumes (Recommended)">
+    Docker-managed storage that provides the best balance of performance, security, and ease of use:
+
+    - **No Permission Issues**: Docker handles all permission management automatically
+    - **Performance**: Optimized for container workloads with better I/O performance
+    - **Production Ready**: Recommended for production deployments

+
+## Common Configuration Options
+
+### Presigned URL Expiration
+
+Palmr. uses temporary URLs (presigned URLs) for secure file access. These URLs expire after a configurable time period to enhance security.
+
+**Default:** 1 hour (3600 seconds)
+
+You can customize this for all storage types (filesystem or S3) by adding:
+
+```yaml
+environment:
+  - PRESIGNED_URL_EXPIRATION=7200 # 2 hours
+```
+
+**When to adjust:**
+
+- **Shorter time (1800 = 30 min):** Higher security, but users may need to refresh download links
+- **Longer time (7200-21600 = 2-6 hours):** Better for large file transfers, but URLs stay valid longer
+- **Default (3600 = 1 hour):** Good balance for most use cases
+
+### File Encryption
+
+For filesystem storage, you can enable file encryption:
+
+```yaml
+environment:
+  - DISABLE_FILESYSTEM_ENCRYPTION=false
+  - ENCRYPTION_KEY=your-secure-32-character-key-here
+```
+
+**Note:** S3 storage handles encryption through your S3 provider's encryption features.
+
+### Chunked Upload Configuration
+
+Palmr supports configurable chunked uploading for large files. You can customize the chunk size by setting the following environment variable:
+
+```yaml
+environment:
+  - NEXT_PUBLIC_UPLOAD_CHUNK_SIZE_MB=100 # Chunk size in MB
+```
+
+**How it works:**
+
+- If `NEXT_PUBLIC_UPLOAD_CHUNK_SIZE_MB` is set, Palmr will use this value (in megabytes) as the chunk size for all file uploads that exceed this threshold.
+- If not set or left empty, Palmr automatically calculates optimal chunk sizes based on file size:
+  - Files ≤ 100MB: uploaded without chunking
+  - Files > 100MB and ≤ 1GB: 75MB chunks
+  - Files > 1GB: 150MB chunks
+
+**When to configure:**
+
+- **Default (not set):** Recommended for most use cases. Palmr will intelligently determine the best chunk size.
+- **Custom value:** Set this if you have specific network conditions or want to optimize for your infrastructure (e.g., slower connections may benefit from smaller chunks like 50MB, while fast networks can handle larger chunks like 200MB, or the upload size per payload may be limited by a proxy like Cloudflare)
+
+---
+
+## Maintenance
+
+### Updates
+
+Keep Palmr up to date with the latest features and security patches:
+
+```bash
+docker-compose pull
+docker-compose up -d
+```
+
+### Backup Your Data
+
+**Named Volumes:**
+
+```bash
+docker run --rm -v palmr_data:/data -v $(pwd):/backup alpine tar czf /backup/palmr-backup.tar.gz -C /data .
+```
+
+**Bind Mounts:**
+
+```bash
+tar czf palmr-backup.tar.gz ./data
+```
+
+### Restore From Backup
+
+**Named Volumes:**
+
+```bash
+docker-compose down
+docker run --rm -v palmr_data:/data -v $(pwd):/backup alpine tar xzf /backup/palmr-backup.tar.gz -C /data
+docker-compose up -d

+## Presigned URL configuration
+
+Palmr. uses presigned URLs to provide secure, temporary access to files stored in **both S3-compatible storage and filesystem storage**. These URLs have a configurable expiration time to balance security and usability.
+
+> **Note:** This configuration applies to **all storage types** (S3, filesystem, etc.), not just S3-compatible storage.
+
+### Understanding presigned URLs
+
+Presigned URLs are temporary URLs that allow direct access to files without exposing storage credentials or requiring authentication. They automatically expire after a specified time period, enhancing security by limiting access duration.
+
+**How it works:**
+
+- **S3 Storage:** URLs are signed by AWS/S3-compatible provider credentials
+- **Filesystem Storage:** URLs use temporary tokens that are validated by Palmr server
+
+**Default behavior:**
+
+- Upload URLs: 1 hour (3600 seconds)
+- Download URLs: 1 hour (3600 seconds)
+
+### Configuring expiration time
+
+You can customize the expiration time using the `PRESIGNED_URL_EXPIRATION` environment variable:
+
+```bash
+# Set URLs to expire after 2 hours (7200 seconds)
+PRESIGNED_URL_EXPIRATION=7200
+
+# Set URLs to expire after 30 minutes (1800 seconds)
+PRESIGNED_URL_EXPIRATION=1800
+
+# Set URLs to expire after 6 hours (21600 seconds)
+PRESIGNED_URL_EXPIRATION=21600
+```
+
+### Choosing the right expiration time
+
+**Shorter expiration (15-30 minutes):**
+
+- [+] Higher security
+- [+] Reduced risk of unauthorized access
+- [-] May interrupt long uploads/downloads
+- [-] Users may need to refresh links more often
+
+**Longer expiration (2-6 hours):**
+
+- [+] Better user experience for large files
+- [+] Fewer interruptions during transfers
+- [-] Longer exposure window if URLs are compromised
+- [-] Potential for increased storage costs if users leave downloads incomplete
+
+**Recommended settings:**
+
+- **High security environments:** 1800 seconds (30 minutes)
+- **Standard usage:** 3600 seconds (1 hour) - default
+- **Large file transfers:** 7200-21600 seconds (2-6 hours)
+
+### Example configurations
+
+**For Backblaze B2 with extended expiration:**
+
+```bash
+ENABLE_S3=true
+S3_ENDPOINT=s3.us-west-002.backblazeb2.com
+S3_USE_SSL=true
+S3_ACCESS_KEY=your-key-id
+S3_SECRET_KEY=your-application-key
+S3_REGION=us-west-002
+S3_BUCKET_NAME=your-bucket-name
+S3_FORCE_PATH_STYLE=false
+PRESIGNED_URL_EXPIRATION=7200  # 2 hours for large file transfers
+```
+
+**For high-security environments:**
+
+```bash
+ENABLE_S3=true
+S3_ENDPOINT=s3.amazonaws.com
+S3_USE_SSL=true
+S3_ACCESS_KEY=your-access-key-id

+**SSL certificate errors (self-signed certificates):**
+
+If you encounter errors like `unable to verify the first certificate` or `UNABLE_TO_VERIFY_LEAF_SIGNATURE`, you're likely using self-signed SSL certificates. This is common with self-hosted MinIO or other S3-compatible services.

+**Solution:**
+Set `S3_REJECT_UNAUTHORIZED=false` in your environment variables to allow self-signed certificates:
