What are Portable Executable (PE) files?
PE files are files that are portable across all Microsoft 32-bit operating systems. The same PE format executable can be executed on any version of Windows 95, 98, Me, NT, and 2000. Therefore, all PE files are executable, but not all executable files are portable.

A good example of a Portable Executable is a screen saver (.scr) file.
