[WiX-users] How does heat maintain consistent GUIDs?

I am curious to know how WiX keeps track of GUIDSs automatically generated for files when we use HeatDirectory. For example, I have a project with the following in my .wixproj file... Target Name=BeforeBuild PropertyGroup WixToolPathC:\SourceControl\WiX39\/WixToolPath

Thanks to everyone for your responses. This helps a great deal and I am most grateful. The link to the suggested post seems to confirm what everyone is saying: ...Took us a long time to get to a algorithm that is stable for Component Guids. Huge win for everyone once it worked. :) – Rob
