How can I change file extensions?

Hi,
this is a common problem - your file extensions are being hidden by the
operating system.

In windows explorer, select the Tools/Folder Options menu item. Then select
the "View" tab. Then, from the center scroll box thingy, uncheck the "Hide
extensions of known file types" box.

Click on the ok button to close the window.

Now, your file extensions should be visible.
