Move big files lightning fast in Windows 8 with TeraCopy

Virtualization expert Rick Vanover says TeraCopy is an easy and great way to easily move big files. Get details about TeraCopy in his review.

In my data center practice, I'm occasionally stuck moving very large files. There was a time when it was rare that I'd see a file larger than a CD or DVD's capacity, but nowadays, I often see multi-terabyte files. There are a couple of reasons why this is the case.

In my professional virtualization practice, I advocate for people to transition to disk-based backups. The other part of this is my emerging practice of working with Hyper-V virtual machines. For me, I'm always moving things around in Hyper-V, and files like a VHD or VHDX disk are actually quite large—much like that of the disk-based backup world.

Simply using Windows Explorer, PowerShell, Robocopy, or the now quite dated RichCopy are good, but myself and others in the virtualization community have come to fancy TeraCopy. It's free for non-commercial use, so it's very easy to try. The paid version, TeraCopy Pro, comes with additional features.

How to use TeraCopy

TeraCopy installs very easily and can optionally be added to the right-click context of Windows systems, which is how I recommend using it. After this is complete, a TeraCopy job can be done as shown in Figure A. (TeraCopy supports Windows 8 x64. The example in this article is Windows Server 2012 R2. Click the images to enlarge them.)

TeraCopy provides you with the option to move the files vs. copying them. Once the files are added and the target path is selected, the jobs are underway (Figure B).

One of the best aspects of TeraCopy is the optional built-in hash checking (Source and Target CRC in the interface) that is done with the files that are moved or copied. It's great that the Target is checked back against the source afterwards in the case of a copy, because you can check to make sure they match. Don't underestimate the file of hash or CRC check of a file, especially very large files. If you do the verify step on TeraCopy, be prepared for it to take a while.

In today's world of storage, there are a lot of different products out there—everything from deduplication (typical for disk-based backups) to converged systems to build-your-own NAS systems—and there can be varied results. Figure C shows the hashing being matched up after the copy.

One of the best aids to a busy (or lazy) administrator is possibly the ability to pause a job. Besides the lazy aspect, this may be very beneficial if you have limited bandwidth, and the task can't run during the business day. That leads me to my wish list of a bandwidth limiter on the I/O, but TeraCopy's objective is to move files fast.
