This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.
See also: List of file formats (alphabetical)

This is a list of file formats organized by type, as can be found on computers. Filename extensions are usually noted in parentheses if they differ from the format name or abbreviation. In theory, using the English alphabet (A–Z) and a three character extension, the number of combinations amounts to 17,576 (26³). If other acceptable characters are included, the maximum number of combinations is 195,112 (26+31)³. Unix-like systems don't have extensions, and Microsoft Windows NT, 95, 98, and Me don't have a three character limit on extensions for 32-bit or 64-bit applications on file systems other than pre-Windows 95/Windows NT 3.5 versions of the FAT file system, so some file system types are given extensions longer than three characters.

Video game storage media

List of the most common filename extensions used when a game's ROM image or storage medium is copied from an original ROM device to an external memory such as hard disk for back up purposes or for making the game playable with an emulator. In the case of cartridge-based software, if the platform specific extension is not used then filename extensions ".rom" or ".bin" are usually used to clarify that the file contains a copy of a content of a ROM. ROM, disk or tape images usually do not consist of a single file or ROM, rather an entire file or ROM structure contained within a single file on the backup medium.

  • N64, V64, Z64, U64, USA, JAP, PAL, EUR, BIN — Nintendo 64 (.n64, .v64, .z64, .u64, .usa, .jap, .pal, .eur, .bin)
