Answer 1

case1: only contain drive C:\

Watch that directory for a "Logs" directory to be created, go to next case.

case2: only contain folder C:\Logs

Watch that directory for a "CustomService" directory to be created, go to next case.

case3: only contain folder C:\Logs\CustomService

Watch that directory for a "Testing" directory to be created, go to next case.

Or, just create the directory.
