Is there any way to "unpack" a pdb file?
I'm sure I could use Calibre to convert a drm-free pdb file to epub or something else for editing but I've found that I have much better results unpacking mobi's and other ebook formats, performing my editing, then using Calibre to convert to my desired final format.
I have an unpack script for mobi that I can use to gain access to the files without the modifications conversion would perform. Is there something similar for ereader (pdb) ebooks or are pdb files more than just a "wrapper"?
Thanks.
