I am using the Deployment Tools Foundation bundled with WiX 3.5. There is an archive that contains a file that I want to update without having to extract it first - the edits are based on user inputs during setup.
How do I obtain a reference to this file, perform the updates, and save the changes to the file without needing to extract it from the archive? The custom action is being written in C#.
I am using Wix v3.5.2415, which is the same version for the DTF assemblies.
