Using Calibre 0.8.66 Portable and just upgraded to 0.8.67 portable
I'm new to this program and I have a problem of duplicate book files such as "unknown" in so many "unknown" folders after I change the author name from unknown to a specific one or change the author name from a wrong one to a new one.
Is there any steps I have done wrong doing so therefore I ended up so many folders like "unknown" or something else where the duplicate book files exist?
Or I cannot find a proper way to get rid off these "orphan" folders if there is a method for that since the program itself should not have duplicated them in the first place
I have the following ultimate questions:
1) How can I safely remove the "orphan" folders and its duplicate books without damaging or deleting the original copies of the books?
2) How can I make sure it doesn't happen again in future author name changes?
3) I need a "find duplicates" plugin also searches orphan folders and get rid off them with their contents safely as the current "find duplicates" plugin doesn't handle them. Any suggestions please?
