How To Enable File Extensions In Windows

file extensions

Windows by default hides all file extensions to keep things easy and simple. This article is a short how to on enabling file extensions in windows so you can convert or change them.

So what are these file extensions?

Normally, PC files have two parts to their file names namely what the file is about i.e., the file description followed by its extension. Let’s take an example to make you understand more clearly. “Resume.doc” is a Microsoft word file which can be made out easily from the “.doc” at the end as its extension. Another example would be “22JumpStreet.mp4” where this is a media file which you can make out easily from the “.mp4” file extension.

Okay, so as you know all this now, you have to begin to see that Windows normally doesn’t display the .doc file extension or the .mp4 file extension because it deems it unnecessary. What I mean here is you only get to see the file description and be void of the file format. For example, here you only get to see “22JumpStreet”and “Resume” and not “22JumpStreet.mp4” and “Resume.doc”.

Oh and you might think that renaming it with something other than the current format would change the file format to a new one. But no, renaming it would only append or add the text you’ve written to the file description instead of making changes to the file format. No, your file format remains the same.

If you wanted to have the format converted into another one, you might use an appropriate proper software to get the conversion done. You could also make use of iTunes to convert the audio files or open a .doc format file extension in a word file to convert into another format such as .docx, etc.

Now we have the big question of how to enable the file extensions in the Windows explorer for windows. Let’s see them one after the other.
