Three simple ways to open a RAR file quickly:
1. Double click a RAR file in the Finder or on the Desktop, no need to launch the app firstly.
2. Drag and drop a RAR file to the app's window.
3. Click "choose file" text link on the app's window and browse the RAR file.
You will be asked for the password if the RAR file is password-protected.
After that, the app starts extracting the RAR file immediately. You do not need to do things like choosing output folder, clicking "Extract" button, etc. All done
