Learning file extensions takes time, and there's no need to memorise them all immediately. But having them show in Windows allows you to become familiar with a key aspect of safe computing for intermediate computer users.

Despite file extension's limitations and complexity, extensions are so tightly integrated into every component of programming, that for the time being they are here to stay.

Of course we can instruct you on site in using file extensions sensibly! Just call us for more information.
