Yes, you can automate the whole update building process here: Building from Commandline
Let's say I start with empty update 1.0.0.1
I then create update 1.0.0.2 and add the following file to my program folder.A.txt
The problem is, that I am now stuck having to manually add that file A.txt to every following update.If I want to create update 1.0.0.3, and if I don't include A.txt, wyUpdate will remove the file from target system.
I'm guessing it's like that by design, because otherwise you would have no other way to remove files. My question is if there is some sort of way where wyBuilder can automatically copy file changes from previous update revision? Having to do it manually every single time is very error prone, especially when the number of files/locations grows over time.
Or am I missing something here?

Is there any automatic way to dump GUI project into xml file, or do I have to create xml file from scratch?
You have to make it from scratch. But if you're automating the creation of updates then also automate the creation of the XML file.
