Conkurs ISO too big

Hey Im trying to burn a copy of my conkurs disc being it has seen better days and is about ready to die, I FTP'd it (the D: folder) back to my PC and used Qwix on it to create the ISO once finished tried to burn with nero and the image is over 4.7GB? Is this correct I have never ran into this in the past when I click on properties of the Folder that has the extracted contents its 4.4GB any suggestions?
thanx

 

delete the dummy files.

 

I deleted the dashboard update and one fmv and it works fine

 

alright i know exactly what your talking about, Awsome thanks

 

If the ISO is really big, burn on a Dual Layered disk.
