Just wanted to drop a line of respect towards TeraCopy, which i'm using to replace the standard copy facility in Windows Explorer.
It's a 'does what it says on the tin' kind of applications, simply integrates into Explorer, doesnt require any extra button presses (crucial), but gives either just a little bit extra info (default view) or alot of extra info as needed.
Plus, you can stack up transfers really simply.
Been using it so far for about a week with Windows 7 Home Premium 64bit, and no negative aspects arisen so far
