Here’s a quick pointer. If you want an CD/DVD ISO Image Creator that does just what it’s intended to do, you should try this fantastic freeware named LC ISO Creator.
It’s this incredibly tiny download (14kb compressed) and runs straight out of box – i.e. no installation is required. It doesn’t require any crappy driver installation either. This can make it an invaluable addition to the PortableApps Suite.
The interface is very minimalistic and doesn’t sport any Settings or Options dialog. It took me around 9 minutes to convert a 3GB DVD into it’s ISO counterpart – pretty good for such compact coding. It even support Unicode. Your only qualm might be that it cannot handle copy-protected disks. Who cares! There are plenty of specialised tools for that.
This one’s headed straight for my PortableApps folder on my USB key.
