ISBN.ext

[Artha]

I have read that one can't change the folder structure of the Library. Yet, I would like to have a listing where all files are named ISBN.ext where $ext is the actual extension, reflecting file contents. Is this possible?

If you want a listing, you'd have to look at the Catalog options. I have no idea if that's possible, as I don't use Catalogs. If you want to export the files to that format, yes, you can do that, but you'd have a duplicate set of ebooks. If you want to change the Calibre library - you can't. Does that help?

Good point. Calibredb is book based, while the user wanted a format based list, but calibredb will list both the isbn field and the formats field, so with some manipulation they could get the requested list. It wasn't clear to me if the question was really about a "list" or about changing actual filenames in the library structure.

I believe --Search: fills the bill

Yes, one search for each format, plus some jiggering of the output to get the list in the form desired of isbn.FMT, but I'm still not clear why one would want such a list.

Me neither

ISBN is per MEDIA format, AND per release.
NOT per title.

HC ISBN 1
Trade Paper ISBN 2
Mass Market Paper ISBN 3, reprint new cover ISBN 4
Audio book...

Is it possible to change the actual file structure once in place?

No - Calibre's internal file structure inside the library cannot be changed. Calibre uses a naming structure based on the values in the title and authors fields for each book.

The only time you can control filenames is when you export files from the Calibre library.
