FILExt's answer:
FILExt was established in 2000 by Tom Simondi in California and is now based in the heart of Europe. In the 1990s, Tom Simondi worked mainly in computer support, sharing his knowledge with the Internet community. A single file extension page on 'Computer Knowledge' became particularly popular, because this website contained not only the appropriate description but also links to the software manufacturers. 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.
FILExt's answer:
FILExt.com primarily uses Microsoft technologies like ASP.NET for its server-side scripting.
FILExt's answer:
Some of FILExt's biggest customers are Fortune Global 500 companies.

Learned regex in the 90's from the Perl documentation, or possibly one of the oreilly perl references. That was a time where printed language references were more convenient than searching the internet. Perl still includes a shell component for accessing it's documentation, that was invaluable in those ancient times.

I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches.
