Be in control
In case of a copy error TeraCopy will try to recover. If unable to recover in the worst case scenario it will simply skip the problematic file, not terminating the entire transfer.

File verification
TeraCopy can verify files after they have been copied to ensure that they are identical. This is done by comparing hashes of source and target files.
Supported algorithms: MD5, SHA-1, SHA-256, and SHA-512.
Integration with Finder
TeraCopy allows you to quickly select a folder that is currently open in Finder and use it as a destination.
Faster workflow
