Hi all!
I've been using Calibre for years now, and really like the product. However, I have run into an issue where I'm stuck and am looking for any help that someone can provide. I have several thousand books in my database, and it was working so well for that, that I have also added in a few thousand "other" things (mostly .jpg's, some .mp3's etc.). This was all working very well until yesterday when I ran a "Check Library" and it found my database was corrupted. No problem, I said, and ran a "Restore database". This seemed to work very well for the books, but then when I ran another "Check Library" it says that I have a few thousand files with no valid format (all the .jpgs, etc.). All those files seem to be there, and it recognizes the folder, but the .jpg file is not loaded into Calibre. So, then I went back to a backup file that was done on Sunday. This database file loads up fine, and seems to have all of the data for most of the ,jpg files, but of course it doesn't have entries for the 200 new books I put in since Sunday, a "Check Library" run on that database reports 200 "extra titles" and "Extra authors". I was hoping there would be to re-add the missing books, but it doesn't appear that there is.
So, as best as I can figure out, I'll either have to re-add 2000 .jpg files into the restored database file, or re-add 200 books into the backup database file. Are there any other options? Is there some easy way to re-connect the existing .jpg files to their entries in the database?
Any advice that anyone has would be greatly appreciated.

Thanks and Regards,
MS
