Extension Changer

Extension Changer is a basic application that provides a very simple way to change a file extension with just a few clicks.
Although such a task can always be performed straight from Windows, users looking for a faster way to change file extensions can always rely on Extension Changer.
With a minimal interface that only prompts you to input the new file extension, Extension Changer provides no other configuration screen, so the whole program is just as simple as the built-in Windows feature.
Although it may lead you into believing that it's a file conversion software, Extension Changer does nothing more than to change the extension of any file on your computer, regardless if it's a song, a photo or an executable.
While the main window is quite simple, Extension Changer also places an icon in the Windows Context Menu, letting you right click any file stored on the local disks and change its extension instantly.
Extension Changer works like a charm on most Windows versions, but administrator privileges are required on Windows 7. Plus, we've noticed some compatibility issues on this particular operating system, as the program sometimes freezes all of a sudden.
Otherwise, it's just an app that performs a simple task, without the need for other configuration screens and help manuals.
To sum up, Extension Changer is the easiest way to change a file extension, targeting beginners who don't wish to rely on the built-in Windows tool every time they wish to change an extension.
