I was unable to detect a question or request in your post, so it is difficult to guess what you expect in response.

You seem to have ignored the advice on avoiding the error-prone drive mapping, (writing directly to a UNC path is the recommended alternative).

Your code appears to be somewhat fragile, but I suppose it could work.

Thank you for reply. I have tried to use the UNC path "\\store\projectnew$" in my script ,but script has error for "$" that is used in the UNC path. My question is that,
1>how can use the UNC path that has $ sign at the end.
2>I want to verify UNC path for write access to the user.
thank you. SMW11
