Create multiple folders once such as 50 at once

The first example on the script's page shows the command that will create 20 numbered folders, My NumFolders 1 through to My NumFolders 20:

CreateFolderEx NAME="My NumFolders" NUMBERED="end=20"

Change the 20 to 50 if you want to create 50 folders instead.

For how to create a button which runs that command, see the Raw Commands section at the top of this guide:
