What's really needed is a replacement for the copy function in Windows.
So far I've been using TotalCopy from http://www.ranvik.net/totalcopy/
. But it crashes, and you can't control how to handle error conditions before they occur, like in the middle of a one hour copy!
So I've made my own, but I've yet to make a proper context menu.
Does anyone know a simpler way of adding a drag and drop context menu, without all the COM noise?
