Using multiple copy streams with Robocopy

This is a quick post to outline a technique I've used to migrate file servers using robocopy - or to be specific, lots of parallel robocopy streams.

The script works best when you have multiple 2nd level sub-directories contained in the root directory. The VBS file below parses the directory names into seperate robocopy command line statements inside a new batch file. When the batch file(s) are run, a seperate robocopy stream is processed for every sub-directory at the same time.

All of the usual robocopy command switches can be used of course. For one off jobs, these multiple parallel streams are much faster than a single stream. It's also great for syncronising file stores if run as a sheduled task.

Here is the code.
