Right-Click Extender turbocharges your right-click menus, allowing you to add such useful options as "copy to folder," encrypt/decrypt, hide file/folder, and Task Manager. Take a look:
Not sure what everything does? Mouse over any option to see a brief description. When you enable (or disable) an option, just click Apply and the change is made immediately.
Best bets: Copy To and Move To, which greatly simplify copying and moving files; and Control Panel and Task Manager, which put those frequently used options just two clicks away.
Right-Click Extender is free. It was designed for Windows 7, but it also works in Vista -- and some features will work in XP as well. [via gHacks]
