Confirm replace when moving assets in folder view


When we drag images from one folder to another within extensis Server 10, and the images have the same file name, a pop-up appears ‘Confirm Replace’. options are Yes, Yes to All, No, Cancel.
There is no option to ‘rename’, and there is no way to tell the difference/similarities between the files. what would be good would be a view that you could see the type of file, the modified date, and size/resolution.

Is this ‘confirm replace’ copy handler a built in portfolio one, is it the windows 7 one from my pc, or the windows server 2003 version from my server?

Namely can we use a different copy handler, or can it be improved or changed? eg with Teracopy?
