Deleting book formats created when sending to device.

Is it possible to stop calibre from keeping formats it creates when sending books to my kindle?

For example, if I have a book in epub format, calibre needs to convert this to a .mobi format and send the .mobi format to the kindle. But it also keeps the .mobi format around which isn't needed.

I am trying to reduce the size of my calibre library or alternatively to stop it growing so quickly, but rather than deleting books, I was wondering if I could get rid of these temporary book formats which I don't need.

Also is there any way of detecting these books so I can delete them manually. I don't want to delete all mobi books, nor assume that just because there is another format, that I want rid of the mobi format.

With a Voyage, I would suggest converting to azw3/KF8. It is a better format.

As for the issue with the books being kept, one of my acquaintances who has multiple ereaders keeps ePub in their library and converts to other formats as needed. For their puposes, they enter 'formats:"=EPUB" and formats:"=AZW3"' (remove the 's) in the search bar to select all books where both ePub and azw3 formats exist and then use the Remove files of a specific format from selected books tool to remove the azw3 format files.

If you see all your books with the selected books highlighted, I would suggest going into Preferences => Searching and checking the Show a quick toggle button... checkbox. This will let you see a button next to the Search button to toggle between only showing selected books and highlighting selected books.

No, there is no way to tell how the mobi format was obtained, AFAIK. You just need to go over the books one by one - unless you have a custom column or a tag with the information about where you got your books.
