fastes way to copy a whole folder with showing the progress?

[Tiemo Hollmann TB]

Hello,

what is the most performing way to copy all files of a folder from DVD to HD
with showing the user a progress? ( about 18.000 files of total 7,5GB) When
making a loop with revcopyfile it is slow, but I can show the user a
progress. When using revcopyfolder it is faster, but I can't show a progress
,what is essential when copying 7,5GB :)

Do you have any other approach for such a task?

Thanks

Tiemo
