TeraCopy is a compact program designed to copy and move files at the maximum possible speed. It verifies files were copied correctly with a checksum. TeraCopy uses dynamically adjusted buffers to reduce seek times. Asynchronous copy speeds up file transfer between two physical hard drives. You can pause copy process at any time to free up system resources and continue with a single click. The paid version of the program (TeraCopy Pro) includes the following features: Copy/move to your... More info »

To the moderators who may not see the point of my adding this as an alternative- it's because of the function that checksums the copy operation.


Checksumming after each and every file/ packet transfer !! Destroying my brand new HDD, with lots of loud noise, for hours of backup. Most destructive program I've met ever over the decades of computing. Now using Fastcopy. Have not yet tried to use other yet. Teracopy cannot copy from one big, fast drive to lots of smaller drives simultaneously. One receiver-drive at a time only. If any of the chained backup drive operation fails, the whole chained backup stops. Waste of time & reliabiliy as well as destroying hardware. Tested just now, using latest hardware & software.




Excuse me, but TeraCopy is crap. Why? Because it fragments the files, even if copied to a blank, freshly formatted hdd. I compared it to UltraCopier, FastCopy and KillCopy. These programs do not unnecessarily fragment the files. And with UltraCopier and KillCopy you can even pre-allocate the disk space to makes sure no fragmentation occurs. However, UltraCopier has a big problem: You cannot start it without admin rights. Also, it crashes Windows Explorer regularly. So, the best alternatives are FastCopy and KillCopy.


Doesn't do excludes (IE exclude file type or file name, exclude specific directories or all sub directories).


I tried it but really can't see the advantage. First, it introduces a stange slack time when I start a copy process and I find me asking if it works or not and second, when the dialog pops up it gives wrong information about the time it needs to copy and progress bar is also incorrect. Perhaps I am the only one experiencing these lacks. Anyway, I deinstalled it again.


Teracopy is such a fantastic software for Windows.. It makes file copy actually work under windows. I desperately wish there were a similar software for Mac.
