How to: Rename a Directory in Visual Basic
The RenameDirectory method of the My.Computer.FileSystem object can be used to rename a directory by supplying the current location and name of the directory, along with the new name for the directory. This method cannot be used to move a directory; use the MoveDirectory method to move and rename the directory.
To rename a directory
Use the My.Computer.FileSystem.RenameDirectory method to rename a directory. The following code renames the Test directory to SecondTest.
My.Computer.FileSystem.RenameDirectory("C:MyDocuments\Test", "SecondTest")
