| Description |
This is a bit of a confusing method. You specify the new TargetDirectoryPath string as the location for moving the current Directory and its contents.
In basic usage, you give the name of the new Directory to be created. It must be different from the current Directory name, and must not exist.
However, if it does exist, then the current directory is moved with its current name to a subdirectory of this existing directory.
Important : when specifying a relative directory, the new directory is relative to the current directory (as given by System.IO.Directory.GetCurrentDirectory) and not the current object folder location! This is not so obvious to see at first!
