FilerFrog

FilerFrog is a small tool that, once installed, will add a new option whenever you right-click on any file or on the desktop itself.

When you select and right-click on several files, you can perform very useful operations like quickly renaming the batch (setting a number or a keyword), encrypting them (setting a password that restricts its use), or extracting them (in the case of compressed files).

Other tools, depending on where you right-click, include automatic image resizing, or organizing the desktop using different (nice-looking) appearances.

FilerFrog is a very comprehensive tool that lets you perform dozens of actions that would normally take you a few minutes in a matter of seconds and with just a single click.
