Windows copy handler enhancement, ExtremeCopy
Standard (freeware, installable) currently at v2.1.0 (the Pro version, at v2.3.0, is shareware), with the portable at v2.0.5 -- I wish Easersoft would unify their versions....
But the later versions look portable if a 'config.ini' is present in the program folder (untested!). ExtremeCopy
claims to be faster than both TeraCopy

ExtremeCopy can integrate into Windows seamlessly as copy tool. ... But the portable version does have one!
