Click at first letter link/shortcut on the top navigation menu and browse for files with extension by the letter it starts with.
In Windows and some other operating systems, file extension is one or several letters at the end of a filename. Usually three or four letters. Filename extensions usually follow a period (dot) and indicate the type of information stored in the file. For example, in the filename program.exe, the extension is EXE, which indicates that the file is an executable program file.
(Depending on the operating system, the punctuation separating the extension from the rest of the file may or may not be considered part of the extension itself.)
File extensions are also used in Microsoft Windows to associate the right applications to open or edit these files. For example, when you double-click at file with extension .txt, Windows starts associated program Notepad (by default). File associations are configurable. Users can change which software applications instaled at computer will open file format of any type.
By default, Windows is configured to hide filename extensions, the (usually three-leter) portion of the filename following the period. Aside from creating a knowledge gap between experienced and inexperienced users, this "feature" also can make it difficult to differentiate files with the same filename prefix. Overall, hiding filename extensions makes Windows more difficult to use.
- Open My Computer, and select Folder Options from the Tools menu (or choose Options from the View menu in Windows 95).
- Click on the View tab, turn off Hide file extensions for known file types, and press OK.
