How to remove an accidentally dropped file shortcut icon from Finder toolbar?

I accidentally dropped a file in the Finder toolbar instead of the destination folder (the ZIP icon on the right of the screenshot):

How can I remove it from the toolbar?

• Hold down ⌘ Command
• Click file and drag it out

Maybe it's different on older versions of the OS, but I'm running OS X Lion, and I have to hold ⌘ + ⌥ and then drag it off.

I had this issue with a bunch of my files, until I realized that like all toolbars, there's a default set. Here's how to restore it:

Control-click (right-click) the menu bar and click Customize Toolbar...

In the sheet that presents itself, drag the default menu bar on top of your "messy" one.

I had this problem, too. Right click, select "customize toolbar," THEN just drag the folder out of the toolbar. No need to hold Cmd.
