Path Finder is the single most useful Finder replacement for OS X that I’ve ever used. You really don’t realize how limited the Finder is until you use something in its place. As an editor you often have to browse many different drives, many different directories and collect and move things from all over your Macintosh. Path Finder makes this a lot easier. It can be customized with different panes, drawers and pop-put windows to help make Finder window switching a thing of the past. It’s really hard to explain all of the good stuff this application does until you take the time to use it yourself. From the Cocoatech website:

Path Finder is an innovative file browser and manager with powerful tools to make you more productive on Mac OS X.

Designed from the ground up for maximum speed and Mac OS X integration, Path Finder has a gorgeous, accessible interface that you can customize to your heart’s content.

There is a demo available so you can give it a try for free. After that $34.95 is a small price to pay for one of the most useful additions to the Mac OS X you can get!
