File Extension – for Windows – Download: All file extensions on one website. Learn what file extensions mean and how to open files in certain formats. Helpful information pages that describe computer file formats and how they relate to formats based mainly on Microsoft Windows platforms and other operating systems such as Apple Mac OS X or Linux / Unix.


Computer file name extensions are usually a combination of three or more letters added to the end of the file name and separated by periods. This determines the coding convention (file format, file type) of the contents. Operating systems like Microsoft Windows register it and assign it to one or more programs. You can then work with the file manager (Windows Explorer, Total Commander, Apple Finder, etc.) by double-clicking on a file and viewing, opening and editing, rotating, converting, or extracting the desired file type. The operating system performs standard actions based on registered file extensions, installed applications, or special user settings. By default, the default application is running. Example: Clicking on a music file (usually MP3) opens a standard player and plays music files.

Display on your Windows operating system

By default, Windows is configured to hide file formats, with parts (usually three digits) of the file name following a period of time. This “function” not only creates a knowledge gap between experienced and inexperienced users, but it can also make it difficult to distinguish files with the same file name prefix.

To view it in Windows, do the following:
– Open “My Computer” and select “Folder Options” from the “Tools” menu (or select “Options” from the “View” menu in Windows 95). If you don’t see the horizontal main menu, you can display it by pressing the Alt key.
– Click the “View” tab and uncheck “Hide file extensions for known file types”. Then press “OK”.
