You enable KITL (KITL=Yes) in your code on a device that's running Windows Embedded Compact 7.
You insert a disc into the CD or DVD drive in the device.
You run the following code on a command line to test the functionality of the CD or DVD drivers and to verify the integrity of data that's read from the CD or DVD drive:

tux -o -d udftest -c "-p \drive_letter_of _ CD_drive_or_DVD_drive"

In this scenario, you receive one of the following error messages:

For a directory file on the disc:

ERROR_ACCESS_DENIED: Test case "PASSED"
