http://gallery.technet.microsoft.com/scriptcenter/Add-Custom-Field-to-Folder-a4f5cf20

This script can be used to add a custom Field/Column to the Folder Content Type of a List or Document Library. This script also has the functionality to remove the Fields and also to list all the Fields in the Folder Content type for a List or Document Library.

The Folder Content Type is sealed by default. We cannot customize it by adding any custom fields from the UI to the default Folder content type. Only way to do is going programmatic way. In real world, not all the SharePoint users are programmers. This PowerShell script enables the SharePoint users/administrators to simply run the script to accomplish the same.

The script shows how to change Windows Store apps default installation location in Windows 8.

As we all know, ​ Windows Store apps default installation location is in driver C. But sometimes the driver C may be full, if we still want to install some big app and that seems impossible. So I think we can change the default Installation Location to ignore this problem.
