Converting the FileSystemObject's Name Property
Definition: Gets or sets the name of the specified file or folder.
You can use the Name property to retrieve the name of a file or folder:
$a = Get-Item C:\Scripts\Test.txt $a.Name
The Name property in PowerShell is read-only. However, setting the FileSystemObject Name property is the same as renaming a file or folder, which is the same as moving a file or folder to the same location but with a new name. This example “renames” C:\temp to C:\temp2:
Move-Item C:\temp C:\temp2
