The first thing you need to know is that developer ArcticLine Software has three different versions of the Folder Marker application to offer. The low-end version is. For no charge whatsoever, the application lets you change a folder’s color, or icon. The icon is based on the folder’s priority or work status. The downside was that during our test, the application refused to work on Windows 7; worked fine on an XP-powered machine though. Is the premium version, and as the name so adequately points out, it is meant to be used by the home user.
