Move-Item throws error when attempting to move directory contents to subfolder within same directory

I have a folder containing files, folders, and a target subfolder. I'm trying to move all contents of the folder into the target subfolder (excluding the target subfolder) using Move-Item. When I do so I get an unexpected "does not exist" error for the target subfolder. Am I misusing the command? Is there another argument that achieves what I want?

PS C:\test> dir


    Directory: C:\test


Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
d-----         6/14/2023   1:06 PM                anotherFolder
d-----         6/14/2023  12:50 PM                subfolder

-a----         6/14/2023  12:50 PM              6 ItemB
-a----         6/14/2023  12:50 PM              6 ItemC


PS C:\test> Move-Item * -Destination subfolder -Exclude subfolder

PS C:\test> dir


    Directory: C:\test


Mode                 LastWriteTime         Length Name

Looks like the move succeeded but I would prefer to not get an error for simple move operation... if I try without the Exclude argument, I get a different error:

PS C:\test> Move-Item * -Destination subfolder
Move-Item : The parameter is incorrect.

PS C:\test>

You're seeing a bug in Windows PowerShell, which has been fixed in PowerShell (Core) 7+.

Workaround:

Get-Item * -Exclude subfolder | Move-Item -Destination subfolder

^{Note: To include hidden files and subfolders, add -Force to the Get-Item call.}

• Get-ChildItem * would work too in this case, but Get-Item * works more predictably across various scenarios.

• Note that you must use * in order for the -Exclude parameter to work as intended (in other words: just Get-ChildItem -Exclude subfolder would not work), because of the counterintuitive way the -Include and -Exclude parameters are implemented - see this answer for background information.
