How to delete an application?

[RichardJECooke]

I tried installing Battle.net in a new Bottle. It installed but didn't work. Reported a bug on Wine Bugzilla.

I tried uninstalling it through the hamburger menu in Bottles. Nothing happens. It stays in the list.

I tried running the installer again. A new program appears called Battle that seems to be the same thing as Battle.net.

I deleted the Bottle, made a new one. But

1. Where are the apps stored on disk so I can delete them manually instead of deleting the entire Bottle?
2. Does deleting the Bottle actually delete the app?
3. This is a bug, obvz.
