And so on

We have given you a lot of information about the extension above, but if you still have confusion about the extension, this step will clear your doubts, let us make an extension.

By the way, you can create any file extension using any notepad, but not all files created by this process will work, but only some files that do not require any other program/data, such as .html .txt file extension etc.

So first of all open your notepad and if you are a mobile user, you can still create these files but for this you will need a code editor app.

So open your notepad and write something normally there, and save the file by pressing ctrl + S and while saving add “.txt” extension at the end of the file’s name, like suppose you want that file by example name If you want to save, while saving you have to type the name like this example.txt

Now because of this extension a txt file of those texts will be created which contains the texts, however if you use wordpad or ms word then while saving automatically the same txt file of that text is created, but only txt from it Extension would have been created but any kind of extension can be created through notepad.

Now we will tell you about the .html extension  , after which there will be no doubt in your mind,

So the first step for this is, get a little knowledge about html and some of their example codes will also be found.

Open the notepad, write the html code, some code will be found in the above link, if you want, you can search on google for more codes, save it by writing / pasting the html codes in notepad and save the file name while saving. Save .html at the end like example.html

After saving the file, open it in the brower, and that file will work exactly like a web page, and remember that if you make a mistake in the html code, an error may come in it, the code with the error will not work. .

In the same way, through notepad, you can create a file of any extension, for example, suppose you have written something on notepad and if you want it to be .html. .txt, .mp4, .mp3, .apk etc. can be saved in Extensions, and notepad will create it in a file of the same extension but all types of extensions will not work when created with notepad.

Rather, only those extensions that contain text or code will work, but not all types of files will work normally, because the process of running different types of file extensions is different.

And if you create files other than text files ie .html, .txt etc. file, such as media file extension then it will not work because graphics is most important for media files, and media file extension only for that. Can be made only by compatible devices, such as from a camera or from an app.

What is extension in computer?
