List of file formats Last updated September 08, 2025
List of computer file types
This is a list of computer file formats , categorized by domain. Some formats are listed under multiple categories.
Each format is identified by a capitalized word that is the format's full or abbreviated name. The typical file name extension used for a format is included in parentheses if it differs from the identifier, ignoring case.
The use of file name extension varies by operating system and file system . Some older file systems, such as File Allocation Table (FAT), limited an extension to 3 characters but modern systems do not. Microsoft operating systems (i.e. MS-DOS and Windows ) depend more on the extension to associate contextual and semantic meaning to a file than Unix -based systems. [ 1]
