File extension is usually three or more letter code at the end of computer file names. File extensions are useful to computer operating systems like Microsoft Windows or Apple MAC OS X and tells to OS what kind of data file they are dealing with and what associated program can open or edit the file.

Show file extensions at your Windows operating system

By default, file extensions are disabled at Windows systems. What you can't see and you don't know about it, can hurt you one day. This allows virus and malicious software writers to distribute executable files disguised as something non-executable. For example, an .exe file might appear to be an common text file (some-filename.txt[.exe] with hidden extension). We think that hidding file extensions by default is wrong decision from Microsoft, but they are still disabled also at new Windows Vista. For more information visit Executable file extensions page.
