Windows keeps a list of known file extensions and open the appropiate program when the file is clicked on. If windows does not know what to use to open it, it will have a generic icon and will prompt you for a program to open it, when you click on it. Be aware that Windows can hide the file extensions, so you won't be able to see it in file lists. You can change this. In explorer, click on 'tools' at the top of the window, then 'folder options', then 'view'. Down the list, you will see a tick box that hides known file extensions. Un-tick it, to see extensions in file lists. On the next tab 'File Types', you can see a list of all the know file extensions and the programs they are associated with.

It is usually separated from the main part of the file name by a ".", but some operating system have used different characters.Most file extensions today are 3 characters long (e.g. txt, exe, jpg, mpg), but different operating systems have used file extensions as short as 2 characters to as long as 80 characters.Some operating systems do not make use of file extensions.
