file-transfernetworkingwindows 7
I have a big file, and I wanted to copy it to the other machine. (Both runs on Windows 7 x64.)
The network speed is terrible, so it took hours to get even 25gigs copied over. And then, the network died.
Now I would like to continue the transfer, but I used Total Commander. It can overwrite the file and such, but I want to continue. I'd prefer to continue, and keep the already copied portion.
What software can do this?
I've checked Robocopy, TeraCopy and Total Commander. No luck so far.
I'm not sure if you're still having this problem but I found this post after having the exact same issue.
I have the same motherboard as you and I'm using a 64-bit installation of Windows 7 connected to my home network using gigabit Ethernet.
I managed to find a solution after reading another super user question and some experimentation:
I went to the configuration screen of my network adapter and changed the following configuration settings:
I guess this is a driver issue. I haven't scouted out for an updated driver so I'm not sure if there is a newer version (and whether this issue is fixed).
This has solved this frustrating problem for me. I hope it helps you.
I went into my router settings and changed Wi-Fi Channel Bandwidth from 20 Mhz to 80 Mhz and my speed more than doubled. Files are transferring at 4x, and speedtest shows a 2x speed boost.
I didn't know it, but apparently AC Gigabit only functions with a 80Mhz bandwidth. So in other words, there are settings on a gigabit router that literally make it into a slower router. Who knew.

I don't believe that any program exists that can resume a copy started by a different program. To resume a partial transfer you would have to use the same program that started it, assuming it supports that (and it sounds like yours doesn't). With a network that flaky, I would suggest copying it via USB drive. If you don't have a USB drive large enough to fit the entire file, you can break it up using a tool like File Splitter and transfer it a piece at a time. Actually, doing it this way and using two drives (1 to copy from source and 1 to copy to destination, simultaneously) would effectively double your throughput.
