What changes does Calibre make when adding books
Hi,

I'm new to Calibre (but starting to get the hang of it) and I noticed that when I add books to Calibre, it makes changes to the original file. In this case I downloaded a book from Amazon, added it to Calibre (but did not convert), and when doing a file compare between that and the version stored in the Calibre directory, the two are different.

Do you have a DRM removal plugin installed? If so, that makes changes. Otherwise, calibre shouldn't be making changes unless you do a conversion or update the embedded metadata.

calibre makes no changes when adding books unless you install third party plugins such as the drm removal plugin
