@timconsidine said in Apps for file management/sharing/syncing:
Cubby is also long standing, but doesn't have desktop apps.
I started on an android app - https://git.cloudron.io/cubby/cubby-android/ . It will take some time to get it polished but it will get there.
By desktop app, do you mean a desktop syncer? I connect via webdav on linux and while not a "syncer" , it gives similar functionality. But I am happy to hear opinions on how important a desktop syncer is these days.
