Orca - Add changeable Files

Hi,

I have created a transform using Orca on a Windows 7 PC, and deployed it to my workstations.

Once deployed, I then add extra information to one of the ini files (i.e. to contains the workstation and phone number which is unique to that station). After I do this, the file goes back to how it was originally (repairs itself). How to I remove this msi function in Orca for this particular file so that it doesn't care if I alter it?

Thanks

Jaz
