This is a really small utility that allows you to move files across a network with pause and resume functionality. I have used this multiple times when moving large files across a very slow uplink 100mbit from one site to another.
This utility runs like a portable app. You do not install it, just double click on the “copyfile.exe” and it opens up. It creates two other files in the same directory where it keeps tracking info. Select Source/Destination then click Add, it will add it below as a job. You can add multiple jobs. The resume option will be visible only when the transfer fails.
