Yahya,
| But I still didn't understand how can I make use of the whole 4GB of
memory.
As David, Sean, and I have stated you cannot per se until .NET 2.0 64-Bit
edition.
Depending on which server you are running, you can enable .NET 1.1 to use
3GB if your server OS supports it. For details start with "/3GB switch" at:

I would review the algorithm I was using to copy the data to see if there
was one that did not require such high memory requirements. Such as reading
& writing 1M chunks at a time.
Hope this helps
