Historical and current file formats
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.

or .text

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
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.
