I KNOW this sounds strange but this SIMPLE operation seems to be beyond simple:
$SourcePath = '\\remoteserver\driveletter$\path with spaces\folder'
$destpath = localdriverletter:\folder
robocopy $SourcePath $destpath /e
...and this fails with...
ERROR : No Source Directory Specified.
...and YES the path is there... NOTE: Elevation isn't the issue and the PowerShell is in Admin mode What I have to do is open explorer and drag-n-drop to ensure the sizes match.
