Ok,
My system are Win2000 Professional US Version on Compaq PC Workstation without any program. I'm copying from DVD to HD and the problem is specified in the my question.

First, do you have enough free HDD space?
For some copy commands, you need 2* the file space for the transfer.

Next, if these DVD's are nearly full, you are exceeding the size of files that the copy commands were designed to handle.

I suggestthat you write a script or program to copy the data files in small logical groups, and run the script to copy the DVDs onto the hard drives.

But my problem is to know why the system is more slowly with the gui, because the xcopy copy my DVD with 4.5GB of files. What is the maximum size of files that the copy commands can copy?

Sorry, I misunderstood your question.

When you copy in DOS mode (xcopy) you simply copy the files, and you are not using the Windows GUI and it's overhead.

When you copy within Windows, numerous features(?) of the GUI slow down the process.First, you have the file transfer animation.
Then if file indexing is enabled, every file is added to the index.
On top of this, is the normal monitoring that Windows does on any file operations just to help you out.

As to size or number of files to be transferred, that depends on available resources. The less RAM that you have, and the less free HDD space, the slower the transfer will be as Windows constantly resizes the paging file.
