File format extensions

This is a simple list of file name extensions or suffixes that indicate the format or usage of a file, and a brief description of that format. Click on the button above corresponding to the first letter in the suffix (in some older browsers that might not work, then try this).

The list is far from complete, but with your valuable help it just might get pretty close!  Please send your additions, comments etc by e-mail to the address pekkaburncreek.net. Thanks!

Can't find what you're looking for? Try FILExt or Wotsit's Format

One way of getting a quite complete list for the UNIX/Linux Operating Systems would be parsing the types from all files named *mime*, e.g. locate mime | wc -l.

In MS Windows, try the ASSOC command (invoke from Command Prompt). This displays or modifies file extension associations:

ASSOC [.ext[=[fileType]]]

  .ext      Specifies the file extension to associate the file type with
  fileType  Specifies the file type to associate with the file extension

Type ASSOC without parameters to display the current file associations.
If ASSOC is invoked with just a file extension, it displays the current
file association for that file extension.  Specify nothing for the file
type and the command will delete the association for the file extension.
