File Extension Resource (Click this header to read blog)

This is the site I’ve used for years to look up unknown file extensions I encounter occasionally. They usually have an answer for the what software creates and uses the extension I find on my computer. I highly recommend it.

clipped from filext.com FILExt – The File Extension Source How do I Use FILExt? FILExt is a database of file extensions and the various programs that use them. If you know the file extension you want to learn about simply enter it into the search box on the left and click on the Search button. If it’s in any of the FILExt databases the data we have on that file extension will be shown on a results page. If it’s not in any of the databases you will be given a link to a page with hints on how to do further research. Don’t search on terms; just file extensions and only one at a time please. There will be another search box on the results page if you have multiple searches to do.
