What PDB and MOBI files are

PDB

PDB (Palm Database) is the file format Palm OS handhelds used for their data, including ebooks in variants such as PalmDOC and eReader. It dates from the mid-1990s and few modern devices read it, so PDB books are best converted to EPUB.

MOBI

MOBI is an ebook format originally developed for Mobipocket Reader and later adopted by Amazon Kindle. It supports basic formatting, images, and DRM protection for digital book distribution.
