 the commandline uploader [up2k.py](https://github.com/9001/copyparty/tree/hovudstraum/bin#up2kpy) with `--dr` is the best way to sync a folder to copyparty; verifies checksums and does files in parallel, and deletes unexpected files on the server after upload has finished which makes file-renames really cheap (it'll rename serverside and skip uploading)
 
-alternatively there is [rclone](./docs/rclone.md) which allows for bidirectional sync and is *way* more flexible (stream files straight from sftp/s3/gcs to copyparty for instance), although syncing to copyparty is about 5x slower than up2k.py if you have many small files in particular
