CopyFile question

I have a bunch of "client PC" that copy a file from the "Server" using
CopyFile API. If I put the file in a "Compressed" folder on the server and
clients, is CopyFile smart enough to Not decompress and compress to the
destination folder? I don't know of a way to observe the behavior, do you ?

Thanks

If the file is highly compressible, and you're transferring across the
wire, you could obverve the "bytes transferred" metric from PerfMon. A
distinctly smaller number would indicate that it's copying compressed.

I've never checked it, but I doubt that it does. Too many possible
confounding factors.
