1 Write a simple text file as shown below & save it as WhateverYouWant.bat - this is a "batch file"
MD NewFolder1
MD NewFolder2
MD NewFolder3
& so on
2 Put the batch file somewhere convenient as a permanent home [assuming that you are going to use it several times in different locations]
3 Copy the batch file to the folder where you want to create the subfolders this time
4 Double-click the batch file to run it
5 Check results & delete the local copy of the batch file
Or have I misunderstood your requirement?
