About

I wanted something between "copy files by hand" and a full cloud drive. Lemon Drive watches a folder, splits changed files into content-addressed chunks, and uploads only the chunks the server doesn't have yet.

How it works

1. A client scans the folder and builds a manifest of file paths, sizes and chunk hashes.
2. It asks the server which chunks are missing and uploads just those.
3. Other devices fetch the new manifest and download what changed.

Status

Personal use only. It has worked for my own photos and notes for a while, but it isn't packaged for anyone else, and there are no plans to offer it as a service.
