I've been using calibre for many years, and have never encountered what I describe in the title. It came about not with the current version, but when I installed the current version on a new computer. My guess would be this is a user-error issue. That I haven't ticked a box. Still, I don't recall this issue existing previously, and I've been using Calibre for over a decade.
The issue:
When I merge file formats, say a pdf and an epub, it creates a folder titled "data". In that folder it's nothing more than the cover image, named "cover-001.jpg"
Note also that in the Book Details column on the right, under Folders it says: Book Files, Data Files. The Data File is not the opf. It is the extra cover image.
If anyone could tell me what box to tick off to prevent this extra folder from being created, I'd appreciate it.
This
is the most recent version of calibre running on windows 11, if that makes a difference.
Thank you kindly for any help
