DiskWrangler Browser:
Closeup - Unix view

DiskWrangler's Browser lets you view files and folders on your hard drive and connected volumes. This "Unix" view shows the same files that the Finder (or DiskWrangler's "Normal" view) shows, along with files and folders that belong to OS X's underlying Unix operating system. You can also choose to view "Invisible" and "Invisible and Unix" items.

You can navigate through Browser views, and manipulate files and folders with the mouse, but there are shortcuts for virtually everything. Your fingers rarely need to leave the keyboard.

What do the buttons do?
