I can't get move() to work! [RESOLVED]

[Kasracer]

Dim mov As Directory

            Try
                mov.Move(app & OldFileName, OldPath & OldFileName)
                MessageBox.Show("Sucess!")

I am trying to move a file that will be in the same directory as my program to a system directory but it just won't work. I'm not sure *** is wrong!

app = application.StartupPath
OldFileName = "\text.txt"
OldPath = "C:\WINDOWS"

I used the rename() function to rename something and I am going to replace it with the file that is in the folder with my program. File names in the example are different from what I'm actually doing but it doesn't matter.
