How to copy a file from one folder to another using VBScript

How can I copy a file from one folder to another using VBScript?

I had tried this below one from the information provide on the internet:

dim filesys

set filesys=CreateObject("Scripting.FileSystemObject")

If filesys.FileExists("c:\sourcefolder\anyfile.txt") Then

filesys.CopyFile "c:\sourcefolder\anyfile.txt", "c:\destfolder\"

When I execute this, I get a 'permission denied' error.
