 note:
-* the parser can finally handle `c,e2dsa,e2tsr` so you no longer have to `c,e2dsa:c,e2tsr`
 * `e2tsr` is probably always overkill, since `e2ds`/`e2dsa` would pick up any file modifications and `e2ts` would then reindex those, unless there is a new copyparty version with new parsers and the release note says otherwise
 * the rescan button in the admin panel has no effect unless the volume has `-e2ds` or higher
 * deduplication is possible on windows if you run copyparty as administrator (not saying you should!)
