script to put a document into a specific file location

Hi does anybody know how i can put an altered document into a specific folder location. This document is the configuration file for typequick. When i reimaged the entire office a couple of months ago most came up with a different port number, now that port is no longer useable and so am trying to change the configuration file on these computers to use a different port. This is done by changing the normal configuration file by changing the port number and then this document needs to replace the old document. any help here would be very much appreciated.
