File Format
Name PRC (Palm OS)
Extension(s) .prc, .pdb
MIME Type(s) application/vnd.palm

PRC is an archive-like file format associated with Palm OS. It stores executable code, and/or resource data.

PRC probably stands for Palm Resource, though it is sometimes said to stand for Palm Resource Code, or Palm Resource Compiler.

It is very similar to PDB, but it is not the same format. For example, the resource records that follow the header are 10 bytes each, while for PDB they are 8 bytes each.



The term "PRC" is also associated with PalmDOC and related formats, though PalmDOC is a PDB format, not a PRC format.


In many PRC files, ASCII characters "appl" appear at offset 60. But when they don't, it is not easy to identify a PRC file by its contents.

A few PRC files even have a .pdb file extension. PRC and PDB can be distinguished by the byte at offset 33, which has its low bit set for PRC, and unset for PDB.
