Issue#

You need to mirror the directory structure (but not contents) for a tree.

Resolution#

Execute the following command from the root of your source directory. Adjust the destination variable to suit your tastes: %i will match the first token, %j the second, %k the third, and %l will match everything else.

for /F "tokens=1,2,3* delims=\" %i in ('dir /Ad /B /N /S') do mkdir t:\dest\%l
