I recently backed up a folder with subfolders and files on to a DVD disk
using Roxio data disk creater.

Some how it corrupted the files in that specific folder on the C: Drive and
I can't open them.

It seems in creating a back up for my files, I corrupted them. The DVD was
mailed off to my co-author. He is checking to see if they open. However, I
also backed up the rest of my C: Drive and I am having issues opening up many
of the files. It seems that subfolders will show the files being there, but
they don't open.

Help!
