What is a File Extension

A file extension is the suffix at the end of a file name. It indicates the file type.

Similarly, “vacation01.jpg” is a JPEG image file and “sales.xlsx” is a Microsoft Excel Spreadsheet document file. Your computer has a central registry for each file extensions it has. For each file extension, the registry stores information related to the file definition and the programs that are supposed to open the file.
