TeraCopy is a dynamically adjusted file-copying utility that lets you pause and resume transfers, see skipped bad files at the end of a download, and find out as much information as needed on every piece of the file transferred. While shell integrated and low on system resources, it still manages to prevent copying any unsecure bit of the net to the computer, recommending itself as one of the safest file transfer tools available.
Errors are calculated through CRC checksum verification so that download or upload speeds get fully optimized.
In addition to that, seek the use of buffer adjustment features significantly reduces times. Failed transfers can be fixed by recopying damaged files. Thus there would be no need to start the download process once again.
