Install Output Support Folder

When I run VB package software to create setup.exe and other files, what is the purpose of all the stuff in the "Support" folder?

All the files in the support folder are actually all the files that were stuffed into your cabs & setup.exe file.
There are there so you can add new versions (normally an updated exe file) and then run the BAT file that is in the directory and it will make you a new setup with the new file that you have included in that directory.

It just saves you having to go through the wizard every time you add, say just 1 file.
