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 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 bit or bit applications on file systems other than pre-Windows 95 and Windows NT 3. Some filenames are given extensions longer than three characters. Some file formats, such as.

Most of the vendors signing on for licences are manufacturers of embedded systems or device manufacturers that produce media formatted with exFAT. The entire File Allocation Table FAT family, exFAT included, is used for embedded systems because it is lightweight and is better suited for solutions that have low memory and low power requirements, and can be easily implemented in firmware. The standard exFAT implementation is not journaled and only uses a single file allocation table and free space map. FAT file systems instead used alternating tables, as this allowed recovery of the file system if the media was ejected during a write which occurs frequently in practice with removable media. The optional TexFAT component adds support for additional backup tables and maps, but may not be supported. With the increase of capacity and the increase of data being transferred, the write operation needs to be made more efficient. This is achieved through the introduction of a cluster bitmap and elimination or reduction of writes to the FAT.
