I'm using ImgBurn to backup a users documents and settings from a previous system. Before I did this I copied the files to an external hard drive. The total size ended up being around 9.10 gigs.
When I created an image for these directories in ImgBurn I created and burned to a single DVD.
My questions is was ImgBurn able to compress these files into a single DVD or did it only copy what it was able to fit and leave the rest out. I did a quick comparison of directories and files to see if there was anything missing and it all appeared to be an exact copy.
I just find it a little hard to believe that it went from 9 gig's to a 4.7 gig dvd. In the event that the image was too large for the disc would it have spanned out to a second image?
