Re: Movie server / large scale file copy

["Paul" <paul@xxxxxxxxxxxxxxxxx>]

SNAP also an Exchange admin and often use ESEutil. Most Windows copy
programmes, including Robocopy, do the job buffered which is great for
small files but very bad for large files. In the case of large files you
need to do it unbuffered to get maximum speed and not crash your OS because
it runs out of resources.

Have a look at TeraCopy (http://www.codesector.com/teracopy.php)
it is GUI based reports failures, is unbuffered and shows the transfer
rate, oh and best of all it is free for home-users

maintenance app) to move big files around, because it's faster (on reliable
connections).
