- The .pdb extension can mean several things. The following is
a list of all the formats that .pdb encompasses:
- TomeRadier protected files
- Palm Reader protected files
- ImageViewer Image
- For one file extension, that is quite a few different formats.
NOTE: You may have noticed that this document treats
DOC and .doc as two completely different things. A DOC file
is a format that is used on Pocket PC, Palm and Desktops as
a popular medium for eBooks whereas .doc is a file that Microsoft
Word creates. They are in no way related.
- Some extensions, thankfully, offer a very straightforward explanation
of what they are. These tend to be completely proprietary and
therefore limited to the software that the vendor provides however
discerning what format a file is becomes a much simpler process.
Below in figure 3.2 there is a listing of all the major proprietary
formats and their associated reader.
Common Proprietary Formats:
Microsoft Reader - *.lit TomeRadier - *.tr
Adobe Acrobat - *.pdf
HandStory eBook Reader - *.hsb
Any DOC Reader - *.prc
While the aforementioned formats are very recognizable there are,
as was stated, many that are not - a prime example is .pdb. There
are methods though, for determining what format your file is. To
do this you can either take the manual or automated routes. Since
the automated route is very easy regardless of your platform we
will not delve into it save for saying all you need is the program
pdbhdr from Richard Hartman.
The manual route is a little more complicated and will take the
user a little more time. This process involves taking each .pdb
file and opening it in a text editor, such as Notepad and finding
a specific word. Through using the list in figure 3.3 you will be
able to determine just what type of format this is.

While this may seem terribly complicated at first it is much easier
than one might think. For example, if you were to open Macbeth.pdb
in a text editor and found a word that reads BDOCWrdS it could then
be assumed that it is a WordSmith document and that to open it you
would need the WordSmith program. (See figure 3.4)
