The command-line client does the same for what it saves and sends (`get -R` into a deep folder, the resume file beside it, `put -R` of a deep tree; `test_get_and_put_past_max_path`). What the desktop application saves is not measured | | **Coarse timestamps, local time** | mtime alone is not a change detector. Size plus mtime with tolerance, and rehash when in doubt | | **Watcher reliability** | Change notification drops events under load on Windows, and inotify is unreliable on a FUSE mount. **Periodic reconciliation is mandatory on both platforms** | | **No symlinks, no POSIX permissions** | Simplifications: nothing to defend against, and the node runs as the user anyway | |
