From Philipp Winterberg:

Free RAR Extract Frog is a new extraction tool for RAR-archives that supports spanned archives as well as the decompression of password protected files. Start the extraction of a RAR file by drag-and-drop, double click, or shell integrated context menu. To speed the decompression process up, Free RAR Extract Frog has the option to define a default output folder or a default password or both. Change the program’s skin by simply dropping a JPEG image or screensaver on the image above the short instructions. The package comes with example RAR files, example skins, and short instructions in over 50 languages
