Think Finder is lacking on a few features get PathFinder 5

PathFinder 5 is by far one of the best applications invented for the Macintosh. It broadens the features that Finder has on offer with productivity of it's file browsing and management of applications that truly sets it apart from it predecessor(Finder).

The features that this app has distinguishing it from the finder include:

Dual Pane File Browser

View the contents of two folders or volumes side-by-side in one window.

Drop Stack

Freeze drag & drop operations by placing files into a temporary stack.

Tabs & Bookmarks

Use the best features of a web browser in your file browser.

File List Sorting & Filtering

Sort by folders first, or limit a list of files by name or extension

Command Line tools

Path Finder puts a terminal right in your file browser, and provides a graphical interface to some popular UNIX utilities.

Above features taken from website.

Also Pathfinder has some more minor features that I personally find excellent which include:

• Copy/Move to folder which means no need to click and drag navigating though Finder which takes time as now you can send a file or folder straight in your desired destination.
• A larger variety of toolbar customizations allowing things like secure delete, a print tab and the ability to duplicate files.
• The ability to become less reliant on Finder by changing certain settings helping you to almost completely forget that it was ever their.
