That's an interesting stuff to come up with. I'll check this out. I don't see why this should be anything different than a IE custom button. After all Windows Explorer toolbars are IE toolbars. Regardless of whether it would do any good to have such button available, don't forget that while it makes sense to have such button in the Open/SaveAs Dialog (since the context is always a folder), it doesn't necessarily make sense in Windows Explorer since the context is not always a folder at all (in other words, even with such button available, I am afraid it would be often grayed out). [edit] Here is a nice CLSID to start search for : {0AFACED1-E828-11D1-9187-B532F1E9575D}. It's known as the Folder shortcut component. May be this just needs to be added to one of the registry extension keys to make it appear in the "Toolbar Customize..." box option.[/edit]
