DriveSight

DriveSight is a customizable freeware tool designed by Trilogy Solutions to assist the SharePoint community in analyzing drives, folders and files which may be uploaded into, or indexed by, Microsoft Office SharePoint Server.

DriveSight can analyze both local drives as well as drives across the network, categorizing each file by size, type, age, and whether or not it's indexable or blocked by SharePoint. DriveSight displays the results in real-time during the scan, and generates a comprehensive printable report with tables and charts.
