[wix-users] Detecting whether a file will be removed on uninstall

[Griesshammer, Christoph (GE Healthcare)]

Is there a way to detect whether a file will be removed on uninstall? I have a custom action that I want to run, only if a file will be removed.

Essentially I want to do:
If I will remove file A then unregister file A first.

I know, I know. I shouldn't use a CA to (un)register files, but that's beside the point right now.

Thank you for any help.
