Do you mean you want to read the folder and file names, or every word of every file?
The former are easily checkable in My Computer. Click Start>My Computer, and you'll find your DVD drive listed under Devices with Removable Storage. Double-click on the drive icon and all the files/folders will be listed.
To open any of the files, double-click on it and its associated software will open. The file will then open.
I hope that's what you meant.
