Use the DOS command XCOPY
So if your data were on N: you would use:
xcopy n:\sourcefolder\*.* c:\destination\*.* /e
The /e switch will copy all subdirectories including empty ones.
You can write at .bat file on the fly with NB's FileWrite command and substitute "sourcefolder" with a parameter [SourceFolder], for example, and then call the .bat file using NB's run command. There are lots of way to do this...experiment and you'll be surprised at what you'll discover.
