Can you paste the specific command sequence and errors that are observed?
I just sent you a private message...
If it helps anyone else, the typo was when the directory change was being made in NSH as follows:
Should have been cd /c/temp/backup...
I didn’t not get anything in email or PM from you. I believe I tried something similar to what you described and did not have any issue, other than an error message saying it can’t execute the directory (which was expected)
