Files have different extensions depending on the app that was used to create and format them. Audio files can be in MP3 or WAV format while video files can be in MP4 or MKV, for example. File format is denoted by its extension followed by a dot (.) or period after the file name in a computer. An example can be Word-File.doc. And each file format needs a specific app to open it. But how do you open a file with no extension on Windows?
