Acronym:Program Information File
Contains information used by Windows to run a certain program, including the path the the .EXE file, how much memory to use, and what size the program's window should be.
Originally used by MS-DOS programs. Can serve as a shortcut to an executable file, much like a .LNK file. Microsoft Windows analyzes PIF files with the ShellExecute function and can run them as executable programs.
Do not open a PIF file sent as an e-mail attachment, as it can be used to transmit viruses or other harmful scripts.
