This is very easy to install & use tool and its very good alternate to defualt Windows copying window that pops up.
Generally windows shows current file name which is getting copied, speed of copy, destination & approximate time to finish coping.
Where as I use tera copy, because it actually details out list of each & evey file to be copied. Shows separate status of each file whether it is copied or not. One can skeep bad or erroneous file & continue copy of remaining which is impossible otherwise.
One can also pause & resume coping any time. Its faster too as it uses some kind of buffering mechanism.
It is actually super-fast if I use it for copying over network.
It replaces the native windows shell of copy paste, hence for use it is transparent & one can still use ctrl+C & ctrl+v.
I recommend this tool for all windows user to speed up large amount of data copy.
