File-extensions.org - about this site
File extensions are usually three, four or more letter codes at the end of computer file names that tell to operating system (Microsoft Windows Vista, Windows XP, Windows 95/98/ME/2000,MAC OS X, Linux and Unix operating systems etc.) what kind of file they are dealing with. Tell to OS which applications can automaticaly open or edit the file.
We researched and collected a very large list of the file extensions and many with detailed explanations of each file type and the way they are used today. We have also tried to include a few of the common software programs that are associated with each of these file extension types.
If you find a file in your computer with an unknown file extension, you can look up the information about desired file extension and its file associations using File-extensions.org website.
Simply use the search box in the top-left corner of each page tosearch for a specific file extension. You may also view an alphabetical list of extensions using the starting letters above, or browse extensions by file type categories using the green navigation menu at the left side of the page.

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.
