Ok sorry for not turning on the lights...
But here is a brief description of what it is supposed to do:
When you're using WinUAE and create bootable directories and launch the emulator with that directory then you'll see nothing in workbench. WinAmInfo = Windows Amiga Info. It recurses the subfolders and checks out if the directories have proper .info files assigned. Get my point? If an info is missing then the file is copied to the position so Workbench can peek into the directories instead of peeking around in the dark. Infos are created on the fly on amiga, but not in Windows. That's why this app is needed.
I hope you've got a good enough explanation. But questions will surely arise, so just ask 'em.
