It is rather like a precious steak knife: very specialised and efficient. The tool only opens RAR archives. As fast as possible. One can open a RAR file by drag 'n' drop, double click or shell integrated context menu. To speed the process up, RAR File Open Knife has the option to define a default output folder and a default password.
If selected, RAR File Open Knife automatically creates new subfolders for each RAR archive it opens. The new folders are named automatically after the archive being opened.
The program comes with short instructions in over 50 languages, the engine is highly optimized. In performance tests RAR File Open Knife was 2-11% faster than WinRAR, 7-Zip etc.
