When I copy a file over my network using windows (in this case 7), it seems to use all available bandwidth which means that I can't do anything else on the network while the transfer is in progress. How can I limit the amount of bandwidth that windows uses so that I can keep using my network during file transfers?
Have a look at the robocopy command (use the /? switch for full help). It has the /IPG Inter-Packet Gap switch which adds a delay between each packet (in milliseconds) designed to reduce bandwidth usage.
