File extension or filename suffix is usually three or more letter codes or numbers at the end of computer file names that tell to operating system (Microsoft Windows 7, Windows Vista, Windows XP, Windows 95/98/ME/2000, MAC OS X, Linux/Unix operating systems etc.) what kind of data file they are dealing with. File extension tells to operating system which program can open or edit the file.
We researched and collected a huge searchable file extension list. Our library and file extension dictionary contains thousands of file extensions today. A large number of file type entries have detailed explanation of each file type and the way they are used today and contain linked programs that can view, open, edit, convert or play unknown file you search for.

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.
