Hello! This is the first time I've encountered an issue using calibre. I searched around and I think I've resolved the initial issue, but I have a question about where to go from here. So here's what happened:
Minutes after I added a book to calibre the .epub file went missing. The format showed as being there but when opening the path the file was not in the folder. I have a backup of my library and of this file.
I removed the book in calibre and then re-added it. Then I ran Check Library and found 4 instances where .pdfs were missing from other books (added a long time ago) as well, though the .azw3's (the original formats) were still there for those books.
I'm not synced to anything and my library folder is on an external ssd. After resolving the issues found in Check Library via Fix Marked and then converting the .azw3 files to .pdf again, I ran Restore Database just in case the .db file was corrupt.
So here's where my question comes in. I ran Check Library again and now the old database file metadata_pre_restore.db is showing up under "Invalid Authors". Do I delete this file manually? Do I leave it there and just pretend it's not showing up in Check Library? What do I do? (And did I even handle the issue properly in the first place?) Thanks for any help you can give me!
