Definition(en): P00 is a Commodore 64 emulation format created for use with the PC64 emulator. The extension is normally 'Pxx', where the xx represents a two digit number corresponding to an incremented extension (beginning with P00) where more than one otherwise identically named P00 file exists in a single directory. For example, five files each called 'file' in a single dircetory would have the extensions p00, p01, p02, p03 and p04.
