File extensions and all you need to know about them

Each and every file name in the computer, whether Mac or Android, comes with an extension. The extensions are of mostly three or four characters prefixed by a period (.) sign, also in some cases with spaces.

The extensions are made to indicate the characteristic of the content of the file or the intended use of it. Therefore, by the file extension, you can know what the file does and what software is needed to open that file. File extensions also signify what is stored inside the file.

Software needed for different extensions

In hundreds of file extensions and everyday development of new ones some commonly used file extensions are easily remembered, but no one can remember all of the extensions.

It is even hard to remember half of them and then you need to find which software is there to open that particular extension. Some websites, including Wiki Ext have come up with an idea to solve the problem.

On this particular website they have a search bar in which you put the extension name and click search, you will be shown a list of software needed to operate those files.

So, you can just check if any software for that particular kind of extension is already there in your system or you can download or buy the software needed from the list of software you can use with your Operating System.

Suppose you are using Windows, Linux, Mac, or Android; all of the software programs required to open the particular extension are listed on a page. They are also working 24/7 to add any new extensions that might come out and list the software which can be used to operate those extensions. They have also listed the universal software variants for each extension which can open that file on any operating system.
