Resume failed copy option

[guest]

It would be nice to have the ability to resume copying a file after a failure. I have various video files (typically 1.5 to 2.5G) that I try to replicate every night over a flaky wireless connection. Very often, the connection failes temporarily after 90% of the file has been copied. At that point, it would be nice if when the project is re-started, to only copy the remaining 10% as opposed to starting from the beginning.
