I have downloaded about seven iso's for live cd's.I only have 7Gig of hard drive space and the iso's take up a lot of room at 699Mb a piece. Is there a way to zip or tar them so I can save them on a CD-R ?

There is no way to effectively compress 7 cd's worth of data on one cd-r or even 3 cd-r.

Maybe you could at the most save 1 cd's space, but that is it.

I woud sugest you simply burn the7 cd's on 7 cd-r, they are about 25 cents a piece nowadays.

Reading my last post I see I was miss understood.I want to save them one per CD-R. When I tried to use Roxio Easy CD Creator(Basic Edition) or NTI CD Maker they tell me that I don'd have enough space on my CD-R. That is why I want to compress them.

Ok I see that you are using Windows for this.

I you want to burn them so they fit forget compression that is not possibel.

The solution is to mount the cd's with a virtual drive like Daemon-Tools (freeware on the web).

Ounce mounted the cd's will fit when you use 'copy CD' . NTI or Roxio will see it as a CD to CD copy.

The reason is simple . The iso's seem bigger on the harddrive because of the file system they are on.

I have sucessfully done this many times.

Nero also has a virtual drive and cClone Cd as is witch is called Clone Drive also.
