A Palm OS Database is the normal format in which data is stored on a Palm OS-based device. These devices lack a normal filesystem, and instead store everything as part of a database. The .pdb extension is what ends up on files containing data exported from a Palm device to another system such as a PC. The one other format used on a Palm device is PRC, or Palm Resource Compiler.

Specific formats

The type of data stored in the file is indicated by the type and creator codes, which are two FourCCs (a total of 8 ASCII characters) that appear starting at file offset 60.

There are separate articles for the following formats:

• GrayPaint
• MOBI ("BOOKMOBI")
• Palm Database ImageViewer ("vIMGView")
• PalmDOC ("TEXtREAd")
• PQA ("pqa clpr")
• ScreenShot Hack PDB
• TealPaint PDB ("DataTlPt")
