FF Copy is a file queue transfer manager for windows networks. It allows you to add files to a copy/move transfer queue which will be downloaded one after another. This increases speed in comparison to transferring multiple files / folders at the same time.
In comparison to copying with the windows explorer you can start/stop/pause/resume transfers. If the source becomes unavailable, FF Copy tries to continue the transfer for a while, then goes to the next file in the queue. Once it tried all files it will again resume with the first incomplete file. So you will not loose the whole transfer if the network connection breaks down after 99%!
