List of file formats

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 basic Latin alphabet (A–Z) and numerals (0-9), a three character extension can yield up to 46,656 combinations; (26+10)3. When other acceptable characters are accepted, the maximum number is increased (very possibly to a number consisting of at least six digits). Many operating systems do not limit filenames to a single extension shorter than 4 characters, as was common with some operating systems that supported the FAT file system. Examples of operating systems that do not impose this limit include Unix-like systems. Also, 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. Some filenames are given extensions longer than three characters.

Video game storage media[edit]

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.[8]

  • FDS – Famicom Disk System (.fds)
  • JST – Jnes Save States (.jst)
  • FC? – FCEUX Save States (.fc#, where # is any character, usually a number)
  • FIG – Super Famicom (Japanese releases are rarely .fig, above extensions are more common)
  • SRM – Super NES Saved Data Files (.srm)
  • ZST – ZSNES Save States (.zst, .zs1-.zs9, .z10-.z99)
  • FRZ – Snes9X Save States (.frz, .000-.008)
  • TAP (for tape images without copy protection)
  • Z80,SNA – (for snapshots of the emulator RAM)
  • DSK – (for disk images)
  • T64 – (for tape images without copy protection, considerably smaller than .tap files)
  • D64 – (for disk images)
  • CRT – (for cartridge images)
  • ADZ – GZip-compressed version of the above.
  • DMS – Disk Masher System, previously used as a disk-archiving system native to the Amiga, also supported by emulators.
