OPF files

pah5 · 11-11-2024, 02:48 AM

Hi all,
Suddenly Calibre decided to turn all my book files into OPF files. Am bewildered as to why this has happened but more so the fact I can't open any of my hundreds of books.
Need Help and guidance please
Regards

I think you'll need to give more details.

calibre stores a metadata.opf file internally along with a cover jpeg and the actual book file.

It's possible for calibre to store details about a book even with no book files, in which case there'll just be a metadata.opf and optionally a cover jpeg.
