Well, you have not given a lot of information...but I gather that the reason you can't see the files on the disk is that your current configuration does not have the program that created the files. If you had that program in your computer, you could probably read the disk.
If you give some examples of the file names, the forum might be able to tell you how to read the information.
put the disk in the drive, left click my computer, right click on the disk drive icon you are trying to read, left click explore.
a window should open with the file names. tell us what the names are, and we could maybe suggest what program needs to be installed to read the files.
