I thank you for your assistance. The files are image files of program dvd's so that I don't have to continue to swap dvd's in and out of the drives. I guess to be safe I will leave them alone.
Thanks Again

I have just recently used imgburn to make iso image files on my hard drive. I noticed upon completion I have the ISO file and then beside it a MDS file. What is the MDS file and do I need to keep it in order for the file to work correctly?
Thanks for your assistance
