   This article may be in need of reorganization to comply with Wikipedia's   
   layout guidelines. Please help by editing the article to make improvements 
   to the overall structure. (February 2019) (Learn how and when to remove    
   this template message)                                                     

   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.

   This is a list of file formats used by computers, organized by type.
   Filename extension it is usually noted in parentheses if they differ from
   the file format name or abbreviation. Many operating systems do not limit
   filenames to one extension shorter than 4 characters, as was common with
   some operating systems that supported the File Allocation Table (FAT) file
   system. Examples of operating systems that do not impose this limit
   include Unix-like systems, and Microsoft Windows NT, 95-98, and ME which
   have no three character limit on extensions for 32-bit or 64-bit
   applications on file systems other than pre-Windows 95 and Windows NT 3.5
   versions of the FAT file system. Some filenames are given extensions
   longer than three characters. While MS-DOS and NT always treat the suffix
   after the last period in a file's name as its extension, in UNIX-like
   systems, the final period does not necessarily mean that the text after
   the last period is the file's extension.^[1]

   Some file formats, such as .txt or .text, may be listed multiple times.

Video game storage mediaEdit

   List of the most common filename extensions used when a game's ROM image
   or storage medium is copied from an original read-only memory (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 one file or ROM, rather an entire file or ROM structure
   contained within one file on the backup medium.^[29]
