UnpackX is a little Mac application that will let you unpack disc images and file archives into folders. The supported formats are 7Z, BIN, DAA, ISO, RAR, RAR parts. As for 7Z, DAA and RAR (not RAR parts), UnpackX can work on password-protected files.
UnpackX is very simple to use. If you have disc images to convert into folders, explore the drop-down menu below the orange drop box. If you have RAR archives to unpack, then open the drop-down menu below the blue drop box and choose an action. Or explore the drop-down menu below the green drop box if you have 7zip archives to unpack. After setting the export destination folder and the folder name, then simply drop and drop a disc image or a file archive onto the drop box above.
