Why robocopy can't close when delete folder?

问题

I using robocopy to copy file from a Share folder "\\192.168.1.112\Share" to local folder "C:\test"

This is my code:

                Dim  strCMD="robocopy "\\192.168.1.112\Share" "C:\test" /MIR /NP /NDL /NFL /R:3 /W:1 /DCOPY:T"
                Dim oProcess As New Process()
                Dim oStartInfo As New ProcessStartInfo("cmd.exe", " /C" & strCMD)
                oStartInfo.UseShellExecute = False
                oStartInfo.RedirectStandardOutput = True
                oProcess.StartInfo = oStartInfo
                oProcess.Start()
                oProcess.WaitForExit()

                '++*************************************
            ' Get ouput infor
            '--*************************************
            Dim sOutput As String
            Using oStreamReader As System.IO.StreamReader = oProcess.StandardOutput
                sOutput = oStreamReader.ReadToEnd()
            End Using
            oProcess.Close() 

If folder "C:\test" is empty . it will working ok.

But if "C:\test" exist 1 original folder and 2 copy folder. cmd can't close.

Ex: Share folder:

\\192.168.1.112\Share\Translation

Local folder:

"C:\test\Translation"
"C:\test\Translation - Copy"
"C:\test\Translation - Copy (2)"
