It loads as a table so please give it a moment as some of the lists are quite long. The file extension list you requested is shown on this page. These lists contain basic information: the extension, the name of the program it works with, the specific function of the file, and the company that makes the program. Not all extensions have all of the data. Click on the extension of interest to see the detail page for that extension. Total extensions in this particular list: 6876.
