I love Calibre and it manages my 3000 books very well
I used to just save my books in EPub fomats with it.
However (I don't know why) a few weeks ago I also decided to save all the books as Mobi too.
When backing up my library to an external every do often, used to take 20mins
But now it takes 3 hours!
And I like to have 2 copies!
It must be because of the mobis
Is there any way to remove some of the mobis? It has to be simple lol
