Any way to delete all books of a certain file type?

Canuck_in_Japan · 01-20-2019, 10:22 PM

I used to have a Paperwhite as well as my Kobo readers so when I uploaded my books to the Paperwhite I had it automatically convert to mobi. I have since sold my Paperwhite and no longer need the mobi file types of all of my books. Is there any easy way to delete all mobi files all at once (without deleting the other file types, of course)

Select all books, then right click the remove books button

To add for Kovid's message, then select "remove files of specific format from selected books", click on mobi and wait 2 seconds.
