This is a
list of file formats used by
computers, organized by type.
Filename extensions are usually noted in parentheses if they differ from the
format name or abbreviation. 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 do not 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.
