Official Description

Many of us on Macs work in organizations which commonly communicate files and paths using drive letters (G:pathfile.txt) and UNC paths (\serverpathfile.txt).

Pather seeks to help solve this problem by allowing you to map a drive letter to a network path, but also by automatically converting drive paths for you.

Pather uses OS X's built-in networking capabilities which makes application support consistent throughout your Mac environment. Since Pather uses Finder's built-in support, your existing application and network security settings are fully supported.
