All files on a computer have a name that consists of two parts: the name you give to them, which usually describe the content and the file the extension, which is what defines what type of file it is, and which program can open it. For example: we have a holiday photo which we have named as beach, but it’s full name would be beach.jpeg or beach.png or beach.gif (depending on the image type). Windows hides these extensions by default. If a file doesn’t have extension, Windows usually refuses to recognize. in this case wee need to add the extension in the end of the file (ex: .jpg, .exe etc).We must tell Windows to show the file extension in order to change or add extension to a file.
