I keep my library in MOBI format and delete other formats using "Remove All Formats from Selected Books, Except...". This morning I was using Send to Kindle to duh send something to my Kindle and noticed an EPUB was still in the folder. Curiously, there are no EPUBs listed under "Formats". I looked in the directories of a couple of other recently added titles and noticed the same thing, other formats that weren't deleted.
Why was this not deleted, not listed under Formats and how do I find these other formats to delete them?
Thanks,
tidy library girl
