I fired up an EPUB in Sigil, even found "Count all," but it dissects the book into single HTML files and it seems it wants to find my word on one page only at a time. That's how much familiar I'm with Sigil.

It was easy to convert my ePUBs to TXT with Calibre, but the second part doesn't seem to be so straightforward and a Google search didn't help much, either.

It'll tell you per book, so if you have a kindle with X-ray, you just check each book for the word on X-ray.

Easiest solution.

Thanks, if all else (the above) fails, I may try this one. My old Kindle doesn't have this feature built-in and my first preference is solving the quest with free (as in free software) and open source tools. I'm on a PC.

Hint: as I stated in the thread stater I have the books in EPUB format. With a word processor? That's a little vague for a complete solution.

Thanks to all!
