Read data from DVD of System in XOJO

Can anyone help to tell the procedure for reading data from Cd/DVD inserted in CD/DVD Drive of a system in XOJO. Then Kindly tell me the process.

There is no difference between a CD/DVD and another drive. A FolderItem can be used the same way. What kind of data are you talking about ?

On Windows, Linux, or OS X ?
The various OSes do things differently in handling cd’s & dvd’s
