+# File Expiration Feature - Migration Guide
+
+This guide helps you migrate to the new file expiration feature introduced in Palmr v3.2.5-beta.
+
+## What's New
+
+The file expiration feature allows files to have an optional expiration date. When files expire, they can be automatically deleted by a maintenance script, helping with:
+
+- **Security**: Reducing risk of confidential data exposure
+- **Storage Management**: Automatically freeing up server space
+- **Convenience**: Eliminating the need for manual file deletion
+- **Legal Compliance**: Facilitating adherence to data retention regulations (e.g., GDPR)
+
+## Database Changes
+
+A new optional `expiration` field has been added to the `File` model:
+
+```prisma
+model File {
+  // ... existing fields
+  expiration  DateTime?  // NEW: Optional expiration date
+  // ... existing fields
+}
+```
+
+## Migration Steps
+
+### 1. Backup Your Database
+
+Before running the migration, **always backup your database**:
+
+```bash
+# For SQLite (default)
+cp apps/server/prisma/palmr.db apps/server/prisma/palmr.db.backup
+
+# Or use the built-in backup command if available
+pnpm db:backup
+```
+
+### 2. Run the Migration
+
+The migration will automatically run when you start the server, or you can run it manually:
+
+```bash
+cd apps/server
+pnpm prisma migrate deploy
+```
+
+This adds the `expiration` column to the `files` table. **All existing files will have `null` expiration (never expire).**
+
+### 3. Verify the Migration
+
+Check that the migration was successful:
+
+```bash
+cd apps/server
+pnpm prisma studio
+```
+
+Look at the `files` table and verify the new `expiration` column exists.
+
+## API Changes
+
+### File Registration (Upload)
+
+**Before:**
+```json
+{
+  "name": "document.pdf",
+  "description": "My document",
+  "extension": "pdf",
+  "size": 1024000,
+  "objectName": "user123/document.pdf"
+}
+```
+
+**After (optional expiration):**
+```json
+{
+  "name": "document.pdf",
+  "description": "My document",
+  "extension": "pdf",
+  "size": 1024000,
+  "objectName": "user123/document.pdf",
+  "expiration": "2025-12-31T23:59:59.000Z"
+}
+```
+
+The `expiration` field is **optional** - omitting it or setting it to `null` means the file never expires.
+
+### File Update
+
+You can now update a file's expiration date:
+
+```bash
+PATCH /files/:id
+Content-Type: application/json
+
+{
+  "expiration": "2026-01-31T23:59:59.000Z"
+}
+```
+
+To remove expiration:
+```json
+{
+  "expiration": null
+}
+```
+
+### File Listing
+
+File list responses now include the `expiration` field:
+
+```json
+{
+  "files": [
+    {
+      "id": "file123",
+      "name": "document.pdf",
+      // ... other fields
+      "expiration": "2025-12-31T23:59:59.000Z",
+      "createdAt": "2025-10-21T10:00:00.000Z",
+      "updatedAt": "2025-10-21T10:00:00.000Z"
+    }
+  ]
+}
+```
+
+## Setting Up Automatic Cleanup
+
+The file expiration feature includes a maintenance script that automatically deletes expired files.
+
+### Manual Execution
+
+**Dry-run mode** (preview what would be deleted):
+```bash
+cd apps/server
+pnpm cleanup:expired-files
+```
+
+**Confirm mode** (actually delete):
+```bash
+cd apps/server
+pnpm cleanup:expired-files:confirm
+```
+
+### Automated Scheduling
+
+#### Option 1: Cron Job (Recommended for Linux/Unix)
+
+Add to crontab to run daily at 2 AM:
+
+```bash
+crontab -e
+```
+
+Add this line:
+```
+0 2 * * * cd /path/to/Palmr/apps/server && /usr/bin/pnpm cleanup:expired-files:confirm >> /var/log/palmr-cleanup.log 2>&1
+```
+
+#### Option 2: Systemd Timer (Linux)
+
+Create `/etc/systemd/system/palmr-cleanup.service`:
+```ini
+[Unit]
+Description=Palmr Expired Files Cleanup
+After=network.target
+
+[Service]
+Type=oneshot
+User=palmr
+WorkingDirectory=/path/to/Palmr/apps/server
+ExecStart=/usr/bin/pnpm cleanup:expired-files:confirm
+StandardOutput=journal
+StandardError=journal
+```
+
+Create `/etc/systemd/system/palmr-cleanup.timer`:
+```ini
+[Unit]
+Description=Daily Palmr Cleanup
+Requires=palmr-cleanup.service
+
+[Timer]
+OnCalendar=daily
+OnCalendar=02:00
+Persistent=true
+
+[Install]
+WantedBy=timers.target
+```
+
+Enable:
+```bash
+sudo systemctl enable palmr-cleanup.timer
+sudo systemctl start palmr-cleanup.timer
+```
+
+#### Option 3: Docker Compose
+
+Add a scheduled service to your `docker-compose.yml`:
+
+```yaml
+services:
+  palmr-cleanup:
+    image: palmr:latest
+    command: sh -c "while true; do sleep 86400; pnpm cleanup:expired-files:confirm; done"
+    environment:
+      - DATABASE_URL=file:/data/palmr.db
+    volumes:
+      - ./data:/data
+      - ./uploads:/uploads
+    restart: unless-stopped
+```
+
+Or use an external scheduler with a one-shot container:
+```yaml
+services:
+  palmr-cleanup:
+    image: palmr:latest
+    command: pnpm cleanup:expired-files:confirm
+    environment:
+      - DATABASE_URL=file:/data/palmr.db
+    volumes:
+      - ./data:/data
+      - ./uploads:/uploads
+    restart: "no"
+```
+
+## Backward Compatibility
+
+This feature is **fully backward compatible**:
+
+- Existing files automatically have `expiration = null` (never expire)
+- The `expiration` field is optional in all API endpoints
+- No changes required to existing client code
+- Files without expiration dates continue to work exactly as before
+
+## Client Implementation Examples
+
+### JavaScript/TypeScript
+
+```typescript
+// Upload file with expiration
+const uploadWithExpiration = async (file: File) => {
+  // Set expiration to 30 days from now
+  const expiration = new Date();
+  expiration.setDate(expiration.getDate() + 30);
+
+  const response = await fetch('/api/files', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({
+      name: file.name,
+      extension: file.name.split('.').pop(),
+      size: file.size,
+      objectName: `user/${Date.now()}-${file.name}`,
+      expiration: expiration.toISOString(),
+    }),
+  });
+
+  return response.json();
+};
+
+// Update file expiration
+const updateExpiration = async (fileId: string, days: number) => {
+  const expiration = new Date();
+  expiration.setDate(expiration.getDate() + days);
+
+  const response = await fetch(`/api/files/${fileId}`, {
+    method: 'PATCH',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({
+      expiration: expiration.toISOString(),
+    }),
+  });
+
+  return response.json();
+};
+
+// Remove expiration (make file permanent)
+const removExpiration = async (fileId: string) => {
+  const response = await fetch(`/api/files/${fileId}`, {
+    method: 'PATCH',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({
+      expiration: null,
+    }),
+  });
+
+  return response.json();
+};
+```
+
+### Python
+
+```python
+from datetime import datetime, timedelta
+import requests
+
+# Upload file with expiration
+def upload_with_expiration(file_data):
+    expiration = datetime.utcnow() + timedelta(days=30)
+    
+    response = requests.post('http://localhost:3333/files', json={
+        'name': file_data['name'],
+        'extension': file_data['extension'],
+        'size': file_data['size'],
+        'objectName': file_data['objectName'],
+        'expiration': expiration.isoformat() + 'Z'
+    })
+    
+    return response.json()
+
+# Update expiration
+def update_expiration(file_id, days):
+    expiration = datetime.utcnow() + timedelta(days=days)
+    
+    response = requests.patch(f'http://localhost:3333/files/{file_id}', json={
+        'expiration': expiration.isoformat() + 'Z'
+    })
+    
+    return response.json()
+```
+
+## Best Practices
+
+1. **Start with dry-run**: Always test the cleanup script in dry-run mode first
+2. **Monitor logs**: Keep track of what files are being deleted
+3. **User notifications**: Consider notifying users before their files expire
+4. **Grace period**: Set expiration dates with a buffer for important files
+5. **Backup strategy**: Maintain backups before enabling automatic deletion
+6. **Documentation**: Document your expiration policies for users
+
+## Troubleshooting
+
+### Migration Fails
+
+If the migration fails:
+
+1. Check database connectivity
+2. Ensure you have write permissions
+3. Verify the database file isn't locked
+4. Try running `pnpm prisma migrate reset` (WARNING: this will delete all data)
+
+### Cleanup Script Not Deleting Files
+
+1. Verify files have expiration dates set and are in the past
+2. Check script is running with `--confirm` flag
+3. Review logs for specific errors
+3. Ensure script has permissions to delete from storage
+
+### Need to Rollback
+
+If you need to rollback the migration:
+
+```bash
+cd apps/server
+
+# View migration history
+pnpm prisma migrate status
+
+# Rollback (requires manual SQL for production)
+# SQLite example:
+sqlite3 prisma/palmr.db "ALTER TABLE files DROP COLUMN expiration;"
+```
+
+Note: Prisma doesn't support automatic rollback. You must manually reverse the migration or restore from backup.

+# Palmr Maintenance Scripts
+
+This directory contains maintenance scripts for the Palmr server application.
+
+## Available Scripts
+
+### 1. Cleanup Expired Files (`cleanup-expired-files.ts`)
+
+Automatically deletes files that have reached their expiration date. This script is designed to be run periodically (e.g., via cron job) to maintain storage hygiene and comply with data retention policies.
+
+#### Features
+
+- **Automatic Deletion**: Removes both the file metadata from the database and the actual file from storage
+- **Dry-Run Mode**: Preview what would be deleted without actually removing files
+- **Storage Agnostic**: Works with both filesystem and S3-compatible storage
+- **Detailed Logging**: Provides clear output about what files were found and deleted
+- **Error Handling**: Continues processing even if individual files fail to delete
+
+#### Usage
+
+**Dry-run mode** (preview without deleting):
+```bash
+pnpm cleanup:expired-files
+```
+
+**Confirm mode** (actually delete expired files):
+```bash
+pnpm cleanup:expired-files:confirm
+```
+
+Or directly with tsx:
+```bash
+tsx src/scripts/cleanup-expired-files.ts --confirm
+```
+
+#### Output Example
+
+```
+🧹 Starting expired files cleanup...
+📦 Storage mode: Filesystem
+📊 Found 2 expired files
+
+🗑️  Expired files to be deleted:
+  - document.pdf (2.45 MB) - Expired: 2025-10-20T10:30:00.000Z
+  - image.jpg (1.23 MB) - Expired: 2025-10-21T08:15:00.000Z
+
+🗑️  Deleting expired files...
+  ✓ Deleted: document.pdf
+  ✓ Deleted: image.jpg
+
+✅ Cleanup complete!
+   Deleted: 2 files (3.68 MB)
+```
+
+#### Setting Up Automated Cleanup
+
+To run this script automatically, you can set up a cron job:
+
+##### Using crontab (Linux/Unix)
+
+1. Edit your crontab:
+   ```bash
+   crontab -e
+   ```
+
+2. Add a line to run the cleanup daily at 2 AM:
+   ```
+   0 2 * * * cd /path/to/Palmr/apps/server && pnpm cleanup:expired-files:confirm >> /var/log/palmr-cleanup.log 2>&1
+   ```
+
+##### Using systemd timer (Linux)
+
+1. Create a service file `/etc/systemd/system/palmr-cleanup-expired.service`:
+   ```ini
+   [Unit]
+   Description=Palmr Expired Files Cleanup
+   After=network.target
+
+   [Service]
+   Type=oneshot
+   User=palmr
+   WorkingDirectory=/path/to/Palmr/apps/server
+   ExecStart=/usr/bin/pnpm cleanup:expired-files:confirm
+   StandardOutput=journal
+   StandardError=journal
+   ```
+
+2. Create a timer file `/etc/systemd/system/palmr-cleanup-expired.timer`:
+   ```ini
+   [Unit]
+   Description=Run Palmr Expired Files Cleanup Daily
+   Requires=palmr-cleanup-expired.service
+
+   [Timer]
+   OnCalendar=daily
+   OnCalendar=02:00
+   Persistent=true
+
+   [Install]
+   WantedBy=timers.target
+   ```
+
+3. Enable and start the timer:
+   ```bash
+   sudo systemctl enable palmr-cleanup-expired.timer
+   sudo systemctl start palmr-cleanup-expired.timer
+   ```
+
+##### Using Docker
+
+If running Palmr in Docker, you can add the cleanup command to your compose file or create a separate service:
+
+```yaml
+services:
+  palmr-cleanup:
+    image: palmr:latest
+    command: pnpm cleanup:expired-files:confirm
+    environment:
+      - DATABASE_URL=file:/data/palmr.db
+    volumes:
+      - ./data:/data
+      - ./uploads:/uploads
+    restart: "no"
+```
+
+Then schedule it with your host's cron or a container orchestration tool.
+
+#### Best Practices
+
+1. **Test First**: Always run in dry-run mode first to preview what will be deleted
+2. **Monitor Logs**: Keep track of cleanup operations by logging output
+3. **Regular Schedule**: Run the cleanup at least daily to prevent storage bloat
+4. **Off-Peak Hours**: Schedule cleanup during low-traffic periods
+5. **Backup Strategy**: Ensure you have backups before enabling automatic deletion
+
+### 2. Cleanup Orphan Files (`cleanup-orphan-files.ts`)
+
+Removes file records from the database that no longer have corresponding files in storage. This can happen if files are manually deleted from storage or if an upload fails partway through.
+
+#### Usage
+
+**Dry-run mode**:
+```bash
+pnpm cleanup:orphan-files
+```
+
+**Confirm mode**:
+```bash
+pnpm cleanup:orphan-files:confirm
+```
+
+## File Expiration Feature
+
+Files in Palmr can now have an optional expiration date. When a file expires, it becomes eligible for automatic deletion by the cleanup script.
+
+### Setting Expiration During Upload
+
+When registering a file, include the `expiration` field with an ISO 8601 datetime string:
+
+```json
+{
+  "name": "document.pdf",
+  "description": "Confidential document",
+  "extension": "pdf",
+  "size": 2048000,
+  "objectName": "user123/document.pdf",
+  "expiration": "2025-12-31T23:59:59.000Z"
+}
+```
+
+### Updating File Expiration
+
+You can update a file's expiration date at any time:
+
+```bash
+PATCH /files/:id
+Content-Type: application/json
+
+{
+  "expiration": "2026-01-31T23:59:59.000Z"
+}
+```
+
+To remove an expiration date (file never expires):
+
+```json
+{
+  "expiration": null
+}
+```
+
+### Use Cases
+
+- **Temporary Shares**: Share files that automatically delete after a certain period
+- **Compliance**: Meet data retention requirements (e.g., GDPR)
+- **Storage Management**: Automatically free up space by removing old files
+- **Security**: Reduce risk of sensitive data exposure by limiting file lifetime
+- **Trial Periods**: Automatically clean up files from trial or demo accounts
+
+## Security Considerations
+
+- Scripts run with the same permissions as the application
+- Deleted files cannot be recovered unless backups are in place
+- Always test scripts in a development environment first
+- Monitor script execution and review logs regularly
+- Consider implementing file versioning or soft deletes for critical data
+
+## Troubleshooting
+
+### Script Fails to Connect to Database
+
+Ensure the `DATABASE_URL` environment variable is set correctly in your `.env` file.
+
+### Files Not Being Deleted
+
+1. Check that files actually have an expiration date set
+2. Verify the expiration date is in the past
+3. Ensure the script has appropriate permissions to delete files
+4. Check application logs for specific error messages
+
+### Storage Provider Issues
+
+If using S3-compatible storage, ensure:
+- Credentials are valid and have delete permissions
+- Network connectivity to the S3 endpoint is working
+- Bucket exists and is accessible
+
+## Contributing
+
+When adding new maintenance scripts:
+
+1. Follow the existing naming convention
+2. Include dry-run and confirm modes
+3. Provide clear logging output
+4. Handle errors gracefully
+5. Update this README with usage instructions
