Move-Item Cmdlet can't move items between drives.
COM seems to have the same problem according to:
So this seems indeed to be related to the internal usage of some outdated API calls. This is limiting and disappointing.
How can this shell deserve the name PowerShell if it can't natively (i.e.
without some scripted workarounds) move folders from one drive to another.
Even Windows Explorer could do this 11 years ago (not sure about Fileman.exe
right now...). I don't care about different drives, all I care about are the
provided source and target path names and my files and folders being moved.
