DupTree is a public domain utility that duplicates a HFS directory structure. This is not the same as a copy operation in the Finder - only the directories are created. 

Running instructions are: first select the source directory (folder) or volume. If it’s a directory, a double click opens a folder, “Select” selects it. Then select the target volume or folder, and the duplication will then proceed. Command-period will abort the duplication if necessary.
