## Best Practices for Batch Upload

### Recommended: Upload by Series

**Example Structure:**
```
Folder to upload: ExaSAN-DAS
├── ExaSAN-Carry-12/
│   ├── System_Code_v1.0.bin
│   ├── Boot_Code_v1.0.bin
│   ├── MacOS_10_15_Installer.dmg
│   └── Windows_Installer.exe
├── Max24/
│   ├── System_Code.bin
│   └── Driver_Windows.exe
└── ExaSAN-LTO/
    ├── LTFS_Tools_MacOS.dmg
    └── LTFS_Tools_Windows.exe
```

**Upload Steps:**
1. Select `ExaSAN-DAS` folder
2. All files in subfolders will be uploaded
3. File paths flattened to `/Users/accusys/Downloads/accusys/`

### Upload All 290 Files

**Strategy:**
- Upload one series at a time (6 series)
- Monitor progress for each batch
- Verify SHA256 checksums
- Total estimated time: 10-30 minutes (depends on network)

---

## Limitations

### Current Limitations:
- ⚠️ **No subfolder preservation**: Files flattened to single directory
- ⚠️ **No download URL**: Download service not yet implemented
- ⚠️ **No file metadata**: Filename only (no product/type info)

### Future Improvements:
- ✅ Download URL service (planned)
- ✅ Product/file metadata database (planned)
- ✅ Folder structure preservation (planned)

---

## Troubleshooting

### Upload Fails
- Check user_id is correct
- Verify file permissions
- Check disk space: `df -h /Users/accusys/Downloads/`

### Browser Compatibility Issues
- Use Chrome/Edge for best results
- Enable Firefox setting if needed
- Check browser console for errors

### Large File Upload
- No size limit (tested with 100GB+)
- Progress bar may freeze temporarily
- Wait for completion message
