Previously I described an application/script that enabled you to open two or more Finder windows, stacked side-by-side, on Mac OSX (10.4 or later). This update changes the proportion of the windows the the display of the files to something closer to Path Finder 5; that is, the finder window stacked on the left (Window 1 below) is set to "list view"; Finder Window 2 (right) is set to "column view." Adjust the size of the Finder windows using the "hei"(height) and "wid"(width) properties. The script will also "hide" all other open windows.
You can download the .app version of this file (below) and then drag it to the dock next to your Finder.app icon for a convenient way to open and positioning multiple Finder windows.
Here's the .script:
