I wrote a program to clean up the OPF file in my EPUBs. Being cautious, in addition to saving the cleaned OPF, I save the old OPF with an OPFO suffix. I can then restore (with WinRAR) the old OPF if my cleaning broke anything.

I've just noticed that if I open the cleaned EPUB in SIGIL, and then do a SAVE,
the OPFO file is no longer in the saved EPUB. My question is why? The OPFO isn't hurting anything. Is SIGIL actively getting rid of unnecessary files in the EPUB?
