Changing file extension in Windows
I don’t understand why there are softwares available to change the extension of a file in Windows.
To change the extension of a file do the following:
1] Go to
Control Panel => Folder Options => View
OR
Windows Explorer => Tools => Folder Options =>View
2] Uncheck (if checked) the option

Hide file extensions for known file types
Without Extension:

With Extension:
Actually it is a text document renamed with a .mp3 extension.
Renaming it again using the above method:

Thats it!
If you want you can again choose to hide the extension by the same method.
