Re: Compressing DVD ISO Images

[Raymond Kelly <ray@xxxxxxxxxxxxx>]

Thanks Ian,
I did actually try 'compress' from the command line - and after 2
hours did not complete compressing an image.
Downloaded a product called '7z', and that actually did compress an
image at a steady rate of 1Mb/sec !!. There was a 5% difference an
hour and half later.
It was worth a try but I'll get that terabyte going!!
