Solution to VBK conversion in Calibre with deDRM plugin

[couponsfortabitha]

I'm not sure if this is the best forum to ask but users like me are looking for a published answer to a common problem with Calibre. Y'all, big question and request for someone in the know preferably Apprentice: I have tried for many hours to research using Calibre to convert Vitalsource's VBK format to other formats, although Calibre does not officially recognize the format. There is almost nothing written about this; every forum says to use a different program. But I think that's wrong, because I just successfully converted VBK to EPUB with nice formatting by reassigning the file in the metadata as an AZW3. Is this method common knowledge, and if so, could an Apprentice (or MASTER!) publish about it please somewhere easily retrieved, because Google research does not lead to this conclusion and it's a common unanswered question I see on many comment sections around the community. Thanks! Seems to be a workable solution that needs more hype!

P.S. Also worked with conversion to PDF, results about on par with a normal non-customized conversion from AZW3.

Sounds great! Can you please describe in more details how you did 'reassigning the file in the metadata as an AZW3' ? Many thanks

Please elaborate on this, I've examined the metadata of some VBK files and also imported them to calibre, but the DRM still exists. You cannot convert/change the metadata to my knowledge. Changing the file extension also does nothing to fix this. Are you sure you didn't just have two copies already, one in each format?

@couponsfortabitha I am also very curious as to how you did this.

This is very interesting. @couponsfortabitha, how did you do it?
