Hi. I have lots of downloaded books which I want to rename using the "download metadata" function of Calibre. It was OK at first, but then I realized that downloading metadata changes the checksum of the files. Is it possible to just rename the files without altering their checksum by writing metadata to them? As it is now, I may end up with a lot of duplicates without knowing (the only way to check whether I already have a book is by comparing its checksum with the file I haven't renamed yet, but since renaming them using Calibre's download metadata changes their checksum, that will no longer work). Can I rename files using calibre but without altering them or do I have to do it manually (open the file, see who wrote it and what it's called, search on google, go to amazon's page for the book, click to select and copy the title of the book, click to rename, paste the title, click OK to deal with the characters Windows doesn't like (colons, question marks, etc)?
