After importing the book into Calibre the original filename isn't important any more (if you think it is, you should read this sticky) and all ways to get the books out of Calibre will use the Calibre metadata automatically, so the rename is implicit (if you configure your file name templates to taste).Ĭould you explain what it is what you're trying to do?Īre you sure you are seeing the checksum change from simply downloading metadata? Calibre does not normally update the metadat inside a file (as opposed to its database) unless you do actions such as convert or send to disc/device. I'm trying to understand what you're trying to accomplish, and not having much luck. 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)? 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). It was OK at first, but then I realized that downloading metadata changes the checksum of the files. I have lots of downloaded books which I want to rename using the 'download metadata' function of Calibre.
