TeraCopy is a file transfer utility focused on data integrity, transfer reliability and the ability to pause and resume transfers. It dynamically adjusts buffers to reduce seek times and provides asynchronous copying to reduce overall transfer time between two storage media.^[3]

In case of a transfer error, the utility re-tries multiple times. Eventually, it skips the file and continues processing other files. TeraCopy shows failed file transfers and allows the user to retry failed operations.^[4] Since feedback about a failed transfer is limited to simply "Skipped", a user may struggle to fix the problem. With more detailed information (i.e. file name too long) the user might be able to better recover.

The utility is designed to run as an application or integrated in Windows Explorer to replace its copy and move functions. The author asserts that it has full Unicode support.^[3]

The utility is licensed as freemium. A basic edition is offered as freeware that is restricted to a non-commercial environment. TeraCopy Pro, a shareware version of the utility, adds additional features such as a list of favorite folders for copy destination and the ability to modify the copy queue.^[3]
