TurtleCopy is a command line application, written in C#. It accepts 3 parameters: Source, Destination, and Duration of the copy.
Usage: TurtleCopy.exe SourcePath DestinationPath Duration
SourcePath: The path to the source file, include quotes if filename contains spaces
DestinationPath: The path, including a file name, to which the file should be copied
Duration: The time (in seconds) that it should take to copy the file to the destination
As the file copies it will create and lock a temp file containing a ".filepart" extension.
once the file is complete it will rename it, removing ".filepart" and release the lock.
