PC Magazine has selected Tom's file extension site as one of their Best 100 Undiscovered Sites. Microsoft became aware of this website and integrated it into Windows XP. When XP tried to open a file it did not know how to open it gave the user the option of choosing a local program or go to the Internet to find the answer. The second option resulted in Tom's file extension research page. Due to the great response to this single web page, FILExt.com was launched in 2001.
