Hello, My version of Adobe CS4 Mastercollection finally came in the mail and that thing was bloody expensive and long story short, I don't want my disk getting scratched up like what happened to my copy of Call Of Duty 4. So I was wanting to back up my copy of CS4 in the case that my original gets scratched or dammaged. I copied the files onto a folder in my harddrive and this is the following size of the file... Size: 8.84 GB Size on disk: 8.99 GB I have DVD+R DL but they only hold 8.5GB of space, it would make sence to compress the file in WinRAR but the problem with that is in order to access the files EVERYTIME I will have to wait for WinRAR to exctract and that takes too long. I don't want to leave the files on my HDD because they are too large, is there any way I can back up 8.5GB of the file to a DL and back up the rest to a regular DVD and when I go to install the Adobe installer will say 'please insert disk 2'? I have the following software to use Nero DVD Decrypter PowerISO
