I have two tutorial CDs. Every time when I run the tutorial, it asks me to put CD into CD-ROM. And each CD only be used less than 300 MB.
I want to copy all files in one CD or copy to hard disk, but the two CDs contains same file names and subdirectory names, if copy the second one, it will over-write the first one. It also happens when runing the tutorial CD setup .

Could anyone tell me how to copy these CDs?

Thanks.
