Export your format to disk, then rename it by adding .bak after the file type.zip
example:

Kristine Kathryn Rusch Diving Into the Wreck.epub.bak

Then zip or rar it, drag and drop it into the Book Details panel for that book or go to Add books and use Add file to selected book records.

I've got some ZIP and RAR files that have compressed .epub versions of some books in my Calibre library. I like to keep these compressed files as backup incase the .epub file gets corrupted. When I try to add the compressed file to my books, it appears that Calibre is automatically extracting the contents of the compressed file.

What I'd like is that in the Edit Metadata window, the small box on the right that shows the various formats of the book, for it to show EPUB, MOBI and ZIP/RAR.

If I try to add a compressed file that has MULTIPLE formats inside (i.e. the compressed file contains the EPUB and MOBI versions of the book) then Calibre does add RAR or ZIP as a format in the "Formats" column. But if the compressed file only contains a single format, Calibre just automatically extracts it and the compressed file isn't listed in the "Formats" column.

Is there a way to force Calibre to show the ZIP and/or RAR file in the "Formats" column even if the compressed file only contains a single format?

Thanks in advance.
