I have various hierarchical structures and would like to allow navigation around then using an editor like the Microsoft one found in the explorer address bar below. Is there such a Delphi component? (Paid for or free)?
TAdvExplorerTreeview from TMS might be what your looking for:

Haven't tried by myself but Roy Klever's PathViewer component looks quite interesting.
I have spent the morning writing such a control. Actually, I wrote a very generic, completely virtual base control, from which I later derived a directory browser control:
The source code is published here
Here are some images:
Style := bbsClassic
Style := bbsFlat
Style := bbsHeader
Style := bbsThemed
Style := bbsCommand
Not sure about anything exactly like that but the BergSoft Next Collection includes a path control similar to that (useful for breadcrumb trails and the like)

It's free providing you don't want access to the source. Source is pretty cheap though and it's a one off cost that'll get you all future updates.
