Dear Syncthing community, on the screenshot below you see how all my files look like since a couple of days:
Before that they used to have proper names with normal file endings etc. How come that all their names changed? Can I bring back the old file names, and if yes how? Thanks for your help!
I think I now remember how that happened. Recently Syncthing stopped synchronizing one or two folders. I started to copy the folder manually via the SFTP client of Ubuntu’s built-in file browser. This solved the synchronization problem for Syncthing, but apparently renamed these files somehow. That at least would be my conclusion.
PS: Another conclusion: Next time better ask here what is the problem of not synchronizing files instead of doing these crappy things. Thanks anyway, and sorry for the irritations!
