Converting an ISO to IFO

Hi,
Not sure if this forum is the right place for this problem, but here it is anyway.
I have some ISOs on my hard drive which i want to convert to IFO file formats so that I can open them in VobBlanker. Any help on how to do this 'step by step' avoiding tech speak (i know some things but i'm still new to most of this)would be greatly appreciated.

 

Download DVD shrink and install it.
Run DVD Shrink, click 'File' 'Open Disc Image' and load the .ISO file.

After it loads, click 'Backup', and from the drop-down menu select the hard disk as the backup target, then select a folder to store the files..
