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, 2000, and XP. All PE files are executable, but not all executable files are portable.

A common example of a PE file is a screen saver (.scr) file.
