## Technical Details

### Upload Flow

1. User clicks "Upload Files" button → `showUploadZone()` displays drop zone
2. User selects files or drags & drops → `handleFileSelect()` or `handleDrop()` triggered
3. Files sent via `uploadFiles()` using XMLHttpRequest with FormData
4. Progress bar shows upload percentage
5. On success: Alert shown, zone hidden, files reloaded
6. On error: Error logged and alert displayed

### Folder Creation Flow

1. User clicks "New Folder" button → `showCreateFolderModal()` opens modal
2. User enters folder name → `createFolder()` validates input
3. POST request to `/api/admin/folders` with name and parent_id
4. On success: Alert shown, modal closed, folders/files reloaded
5. On error: Error logged and alert displayed

### API Endpoints Used

- `GET /api/admin/folders` - Load all folders
- `GET /api/admin/uploads?folder_id={id}` - Load files in folder
- `POST /api/admin/upload` - Upload files (multipart/form-data)
- `POST /api/admin/folders` - Create new folder

### Database Tables

- `media_folders` - Stores folder structure
  - id, name, parent_id, path, created_by, created_at, updated_at
- `uploads` - Stores uploaded files
  - id, filename, original_name, file_path, file_size, mime_type, uploaded_by, folder_id, created_at
