How does windows handle file copy operations made across the network via an intermediate machine?

Less of a critical problem, more a  point of interest - someone asked me about this the other day and I realised I had no idea.

When starting a file copying operation in Explorer on PC1 from \\PC2\Share to \\PC3\Share, does the operation go via PC1? Most testing I've seen would indicate yes, but I was thrown when I noticed that moving files between two shares on PC2 was done instantly, i.e. it was known that files were on the same logical disk.

Any info about the logic windows uses for this would be very appreciated. Is there any difference between XP and Vista in this regard?

Thanks in advance

I thought if it was on the same partition, it would do the move instantly.
Different servers from a workstation, it would traverse the full path, including the workstation.
Shouldn't be any different from XP or Vista, except you finally get an option for 'no to all', yay...

Yeah, if it's on different machines it goes via the PC you run the command from.

Thanks both

So, if the files are (a) on the same partition and (b) being moved, not copied, then they move on the remote machine. But copy operations, even on the same remote partition, always go via the PC the command was run from?

If the files are on the same logical disc then it passes through the pc1, else it wont.
