Have you ever asked yourself, “When I drag-and-drop a massive file like a .VHD or a .XIM image between hard drives (i.e. not over the network):”

• Why doesn’t it checkpoint-restart to allow for failures?
• Why does it insist on using slow synchronous file transfer techniques?
• Why does it halt when one file copy fails?

Some know that Robocopy solves a couple of these problems for network-based file transfers, but it doesn’t solve all of them and it’s certainly not a well integrated, GUI-based tool.  Meanwhile vxCopy is useful really only in network file copy scenarios where multiple simultaneous copies are useful to saturate a network connection and useless for drive-to-drive scenarios.

INTRODUCING “TERACOPY”
Teracopy is the shell-extension tool I’ve been searching for over the last year or so.  It’s the USB 2.0 drive owner’s dream and sort of like a RichCopy for large disk-to-disk file transfers. 

• FILE COPY MANAGER
  It is a file copy manager for transfers between drives allowing for lists of files to be moved in an uninterrupted serial fashion, minimizing drive seeks, and maintaining continuity even if one file copy fails.
• DATA STREAMING
  It efficiently streams files between disks asynchronously to accelerate LARGE file copies by minimizing block acknowledgements. 
• CHECKPOINT-RESTART
  It provides fault tolerant checkpoint-restart enabling file copies to stop and continue later, even if the drive gets disconnected in the middle of a file transfer.
• ERROR CHECKING
  It does full CRC checking between file copies to ensure fidelity in transfers
• WINDOWS-INTEGRATED
  For convenience, it also intercepts all drag & drops between file folders made by the user.
• FREE!
