Duplicate files


This is possibly a really silly question, but are there any occasions where Paperpile creates a duplicate copy of a file, eg for annotations or notes?

I’m asking because I’m reaching the limits of my Google Drive storage and while looking for files that I can delete I have come across a significant number of apparent duplicate pdfs in the Paperpile folders. They may well be the result of syncing issues, which I have had at some point, but I’d rather be safe than sorry.


In principle, Paperpile should not create duplicates. If you see files with duplicate names the reason can be that you imported from sources like your hard-drive or Mendeley that contained duplicates. In that case Paperpile attaches all files it finds to one reference (as we don’t know which one you want to keep).

Also the use of some third party Google Drive sync programs may mess things up.

But in general if you want to clean up space going after your PDFs is typically not the most primising. Often there is a video file somewhere which is as big as your whole paper collection. But that’s just a personal experience, your situation could be different of course.
