Does anyone know what these strange book entries are? They're a string of numbers, dashes, letters. [image attached].

I save my Calibre library in Dropbox. I just changed my Dropbox search path from 'everywhere' to 'custom' and pointed it more directly at my Calibre folder. My actual books are still there, but I have lots of these long numbers strings. Looks like there's about 200 of these funny files based on the file count.

I downloaded/opened one and it is a book that I have, but that book has an actual title file entry too. They're all on top as if they're the most recently changed/added files.

Hidden files? Earlier epub versions?
