All files on a computer have file name extensions that tell the computer the type of file (document, spreadsheet, etc.) and the application or program needed to open the file. For example, Microsoft Word documents have a .doc or .docx extension, while Microsoft Excel files have a .xlsx extension. Likewise, audio files have .mp3, .wma, and other types of filename extensions.
