Hello,
When moving my files to a new system install using Dropbox, I found out that some of them haven't synced back. When looking at my web folder, they appear to have 0 bytes. When trying to preview them, I see a 415 error message:

Are my files really "safe", or are they lost forever? I don't see any file history, they aren't in the deleted files either. Is there any way for me to recover those files?
