I think I've been running into trouble because I was trying to edit the epub by first changing the .epub to .zip and then once I finished the edits I'd re-zip the folder then change the extension to .epub.
This method gives me a corrupted file error message when I try to open it in the Sony Library. I'd like to edit the code of the pages without using Sigil because for some reason I find that program confusing to use and there is no way to save all opened tabs at once.
