Hello! I want to know if there's a way for me to know which formats are the original format (the ones I imported to my Calibre library) and which ones are conversions made by Calibre. If there is not an automatic way, I'd like to know how I can add a note to comment about this somewhere that doesn't change the original files. Since I have retail versions of my books, I'd like to not tamper with them in any way, but since I always either convert from epub to azw3 or vice-versa, I don't know which one of the two is the original. That is not really working for me because for archiving/backup purposes I'd like to know which one of them is the original file. Thanks!
