This software is basically for accelerating the speed of copying and moving files. When I copy any file larger than 1GB, it doesn't accelerate the transfer. What can I do? Is there anything wrong with my software or my hard drive?
It's good for files less than 1 GB.
No, there isn't anything wrong with your hard drive. Unfortunately, many TeraCopy users have problems when they are trying to transfer files larger than 1 GB or when they are trying to transfer data to/from an external drive. In order to fix the issue, you can try updating the program to the latest version. If this doesn't help, you can check Software Informer database for an alternative solution.
For copying large files or a bulk of data , you can use Goodsync or Gs Richcopy 360 , both are quick and fast
