[UDF] Dir copy with progress

[SumTingWong]

This code is based off Larry's brilliant _FileSearch UDF. Hope you don't mind Larry .

It's slow so should only be used on fairly small directory structures.

Why not a "Progress bar" within the function?

Maybe another optional param, show or not the progress bar...

Only a suggestion...
