How can data stored using the IE userData Behavior deleted?

I can't find information about how to delete data stored with the IE userData Behavio开发者_C百科r, other than deleting an individual item with JS.

Is it cleared when a user deletes cookies and html 5 localStorage, or does it need to be deleted in some other way?

IE store userData in XP:

C:\Documents and Settings\USERNAME\UserData

or

C:\Documents and Settings\USERNAME\Application Data\Microsoft\Internet Explorer\UserData

Vista/Win7:

C:\Users\USERNAME\AppData\Roaming\Microsoft\Internet Explorer\UserData

You can find folders and *.dat files and XML files containing data In UserData folder. You can delete them directly, and clear cookies or html 5 localStorage will not work.
