Today, I present to you a site that will let you know what software you need to open a file with an extension that you don't know.
(Reminder/FYI, the extensions of the files are in the form of .xxx as .doc, .zip, .txt, ect…)
This site catalog more than 800 extensions file and for each of them, gives a brief description of the extension and offers you the software you need to open your file!
And all the software it offers are free!
How do I? It's simple, from the moment where you know your file extension, you just go find it in the alphabetical list of the top, or even use the search engine that is right!
In short, a small wonder that you will avoid to search on Google what free software is necessary for using a file an unknown extension!
