3000 File Extensions

June 12, 2008 — by Per Christensson

The Sharpened.net File Extensions Reference has now reached the milestone of 3,000 file extensions! As most regular visitors know, the Sharpened.net file extensions database is unique in that it lists detailed information about each file type, including how the file type is used and what programs will open the file. Therefore, each file extension entry can take awhile to research and enter into the database. This is why it has taken several years to enter 3,000 extensions, contrary to the belief that I am lazy, which is only partly true.

My goal is to provide as much useful information as possible for each file association. This means that when you look up an unknown file type in the Sharpened.net File Extensions Reference, you're bound to find the information you need. And while I continue to add new extensions, I also frequently update extensions already in the database. So, if you ever think a file extension should have more information, just let me know!
