how-to-recursively-create-subfolder-in-each-folder-of-a-directory-in-cmd

test.cmd:

@echo off
setlocal
for /f "usebackq tokens=*" %%a in (`dir /b /a:d`) do (
  rem enter the directory
  pushd %%a
  echo In Directory: %%a
  md child
  rem leave the directory
  popd
  )
endlocal

Notes:

• dir /b /a:d is evaluated once, so the list of directories is fixed
• for /f will loop through this fixed list exactly once.

Example output:

> test
In Directory: Documentation
In Directory: subdir
In Directory: test
In Directory: test with space
In Directory: test1

> dir /b /a:d /s child
F:\test\Documentation\child
F:\test\subdir\child
F:\test\test\child
F:\test\test with space\child
F:\test\test1\child
