Learner,
I wouldn't recommend you to use it for zip/rar - files.
It is doing the same as WinZip/WinRar when you want to see the content of the file.
First it extract the file in temporary directory and then open it.
This is not case when you mount the ISO-image. It read the files on fly and you will
not need additional disk free space for temporary files.
