What's the Explorer.exe copy engine in XP?

[revolutn]

One would think this would have been easily Google-able but I'm getting incongruent search results.

Does anyone know what the copy engine used in Windows XP is when you do a Copy/Paste or similar copy function in Windows XP?

And further is there a way to replace it with something better like robocopy so that Explorer.exe natively uses it?

Mostly I'm asking due to network file copy/move functions which suffer or fail completely when there's latency or packet loss.

Thanks,
Rev

Change your tcp settings to be more tolerant of packet loss. Go lookup TcpMaxDataRetransmission and TcpMaxConnectRetransmission.

I wouldn't go above 4 for connect, and wouldn't go above 8 for data. The time between retries is exponential. If it's going to fail after this many retries it's sometimes best to just fail and get it over with instead of waiting all day on a timeout.

It uses the Win32 api's. There isn't a way to swap in a different engine.
