I have 2 Windows computers and 1 Android phone all signed up with my Dropbox account. I want to delete some old photos from my Dropbox account (I already have them manually copied to a different archive folder on my PC that isn't linked with Dropbox. ) When I delete them from the Dropbox folder with one computer, they aren't getting out of Dropbox folder on the other computer or the phone. I wind up with files that have names saying there was 'contention'.
Do I have to delete them from the web-interface to Dropbox?
File > Delete
? Are you deleting a large number of files? Certainly deleting them from the web is an option. I'd experiment a bit.
