PM is an acronym for Perl Module. Files that contain the .pm file extension store modules that hold specific Perl functions.
The PM modules are used by different Perl applications and often contain data that defines the subroutines and variables of the module function or class definitions that can be accessed via method calls. When these PM files are compiled, they are given the .pmc file extension.
The Presentation Manager software application also uses the .pm file suffix. These PM files contain the bitmap graphic files that are used by this presentation program.
The PageMaker software also uses the .pm file extension. The PM files that are used by this program contain document files that have been created within the application.
