I have done some searching within my Ipod Touch and it seems I have located the storage of epubs that I have downloaded from Stanza. After I saw the location, I saw that they were parts only in xhtml format that seems there is a need to compile them.
So I would like to ask if there is a compiler of those xhtml/html files to a single epub where I can edit it, or do I have to do it manually?
P.S. : Have been using Sigil as my ePub editor and definitely helps a lot for me.
