You can use the robocopy command in Windows Command Prompt to copy folders and subfolders without copying files. Here’s how you can do it:

1. Open Command Prompt. You can do this by searching for cmd in the Start menu or by pressing Win + R, typing cmd, and pressing Enter.
2. Use the robocopy command with the /E and /XF * options. The /E option copies all subdirectories (including empty ones) and the /XF * option excludes all files. Here’s an example:

robocopy "source_directory" "destination_directory" /E /XF *

Replace source_directory with the path of the directory you want to copy and destination_directory with the path where you want to copy the directory to.

For example, if you want to copy the directory structure of C:\Users\YourName\Documents to D:\Backup, you would use the following command:

robocopy "C:\Users\YourName\Documents" "D:\Backup" /E /XF *

This will create a copy of the Documents directory structure (including all subfolders) in the Backup directory, but it won’t copy any files.
