I am on a mac and my hard drive came dangerously close to being full. Now I am trying to do a very thorough cleanup. Help me understand what to do about my book files.

- There are a lot of epub files in my Downloads folder, some with names I can read and some without. When I put books into Calibre, Calibre makes a copy so I can delete all the epub files in my Downloads folder, correct?

- I use Sony Reader Library to convert acsm files to epub. Then I bring the epub into Calibre. Again, since Calibre makes a copy of the epub, I could delete all the epubs in Documents / My Books / Reader Library, correct? How about the xml files in there? I guess those are needed for the Reader library database?

- I was also putting all my borrowed library books in Calibre, and then deleting them after reading. But I have discovered that I was only deleting the entry in Calibre, not the epub file.* So now I have a LOT of epub files on my hard drive, that I don't want. Can you think of any way to "look for" these? In other words, find epubs which are NOT in Calibre, in order to delete them? Or do I just have to look at all my epubs and remember which are library books?

*A suggestion to Calibre developers: when I delete a song in iTunes, it asks me if I want to delete the file as well. Same with Lightroom: when I delete a photo from the Lightroom database, it asks me if I want to delete the file. I think Calibre should work the same way.

Thanks for any help!
