Some Mobi Files are PRC, I think, and I remember having some Palm Doc and eReader files that were PRC's too.  |
NatCh is correct - a PDB file may contain thousands of different data formats. Basically a Palm only supports two types of files:
.PDB - Palm Database - used by applications to store data.
.PRC - Palm Resource - used to store data in resource segments.
A resource database may be used to store executable code, data, or both.
A Palm file may be identified only by examining the contents. Each file contains a Creator ID and a File Type. The Creator ID is a 4 character string registered by a developer with Palm and identifies the application that created the file. The file type is another 4 character string selected by the application developer to allow a single application to support multiple file types.
Quite a while ago I created a Windows Explorer shell program to dynamically display the type of a PDB file by hovering the cursor over it in Windows Explorer. I will attach it to this posting in case anyone here uses Windows and is interested. It would be pretty easy to create something like this that could be run from a command line and support multiple OS's - let me know if anyone is interested.
