The P02 file format is a legacy container format developed for the Commodore 64 ecosystem to preserve original filename metadata when transferring data to non-native platforms. It is primarily utilized within the retro-computing community to package software, games, and data for use with Commodore 64 emulators and modern storage interfaces. Although this format is considered safe and contains no executable code for modern operating systems, it remains a historical standard for maintaining file integrity across incompatible file systems.
