If you regularly copy files between the computer and an external USB disk drive, a networked drive like NAS, or another PC on the network, you may find that it slow and occasionally problematic.
Instead of using Explorer in Windows to copy files from one place to another, you might want to take a look at TeraCopy, a free utility that offers many advantages to the normal copy procedure.
One of the claimed advantages of using TeraCopy to copy files is its speed and it is said to outperform Explorer when copying files. When copying 100 MB of files from the internal disk to a NAS (network attached storage) I didn't see much of a speed difference though. There wasn't much difference when copying to another folder on the internal disk drive either.
Perhaps a larger number of files is needed, or a faster network - mine may have been swamped by the network traffic and couldn't go any faster.
This was a slight disappointment, but speed is not the only benefit of TeraCopy and there are many other advantages. For example, there is the option to shut down the computer when the last file has been transferred.
This is useful if you want to back up several gigabytes of files from the PC's disk to an external disk or network location at the end of the day, or to copy files from an external disk or network location to the PC. You can set the copy task running and then walk away, and you don't have to sit there watching an Explorer progress bar creep across the screen until it has finished so that you can switch off the computer.
Another advantage of Teracopy is that files can be tested after being copied to make sure that they are perfect and not corrupted in any way. Transferring lots of files or large files over a flakey network can cause errors, but TeraCopy should catch them.
Files can be moved instead of copied and in this case you really do need TeraCopy's option to verify that the files are OK. It performs a CRC (a type of checksum) to ensure that the files are OK.
Sometimes when reading files an error can occur or there might be a conflict, such as a file in the destination location that has the same name. You can choose what happens in case of errors before starting the copy operation, which is great for unattended copies.
When using Explorer, it will stop at the first sign of a problem and wait for you to choose an action, then stop at the next problem and wait again, but TeraCopy can continue to the end using simple rules. For example, you can choose to overwrite all files at the destination, overwrite only older files, skip all, rename all or resume all.
TeraCopy is a useful tool and it can be installed in portable mode, which means that the folder can be stored anywhere, even on a USB memory stick. This is great and it enables it to be carried in your pocket and used on any computer.
