I recently had an epub with some issues so I ran it through the Calibre converter into another epub and it kept both versions, giving the old one a .original_epub. It didn't fix the problem and I didn't need the re-converted copy so I deleted it (who knows if more stuff broke on the reconversion). Now I just have .original_epub and while it does open in Viewer how do I get it back to .epub so it works correctly with other applications/devices? I tried manually naming it back to .epub but then Calibre loses track of it because it's looking for .original_epub.

On a side note, I've read Calibre can't handle multiple versions of the same format, which is a feature I've wanted to have, but isn't that essentially what is happening here? It seems like I could reconvert an epub (or whatever format you have multiple versions of), then manually swap out the file with another version of the epub and Calibre would track both. Is this a valid workaround or am I missing something?
