Help using calibre

muddyl

I'm trying to convert some ebooks to upload to my tablet.
I'm trying to do it in bilk to save going through them individually.
How do you get it to convert and only save the epub formats as at the moment its saving the epub and the original format meaning I'm having to delete the extra format one by one.

Any idea as this is taking me ages. I have checked a couple of sites but the instructions seemed unclear.

Not sure how to convert and only keep one format (although it may well be possible), but I'm pretty sure you can bulk delete the old formats rather than one at a time. I don't have calibre with me to check, but if you highlight all of the books where you've created an epub version, then right-click, I think there should be an option to remove files of a specific format, you could then select the non-epub version and get rid of them that way?
