METHOD:  File.Copy

Implemented in version 3.0
 
object.Copy destination[, overwrite]

This method makes a copy of the selected file and saves it to the specified destination. The overwrite parameter is a Boolean value - True allows existing files with the same name as destination to be overwritten while False (the default) does not.

Note that after copying a file to a new location the File object still relates to the original file.

Code:
<%
dim filesys, demofile
set filesys = CreateObject ("Scripting.FileSystemObject")
set demofile = filesys.CreateTextFile ("c:\somefile.txt", true)
set demofile = filesys.GetFile("c:\somefile.txt")
demofile.Copy("c:\projects\someotherfile.txt")
%>
