I synced pictures from my Android phone to my Windows computer. It finished and then I deleted the pictures off my phone. Now I see the pictures on my computer are gone too. I need to get my pictures back. How do I get them back?
Did you enable the versioner when setting up that folder… ? Then, you would be lucky because Syncthing retained the deleted files in a hidden folder .stversions (see docs).
Syncthing is bidirectional, so deleting on one side, deletes on the other.
