Here I posted this a while back in the tutorials forum
just change one line like so
xcopy %sname%:\*.doc /S h:\migrate /H /I /C /K /E
xcopy %sname%:\*.* /S h:\migrate /H /I /C /K /E
then remove the rese like this.
install this batch file on the root of each directory and run it.
This will keep the Directory structure intact. Let me know how it works
