DiskSavvy provides a Windows shell extension allowing one to analyze disk space usage directly from the Windows Explorer application.
In order to analyze one or more disks or directories, select the required disks or directories in the Windows Explorer application,
press the right mouse button and select the 'DiskSavvy - Analyze Disk Space' menu item.
In most cases, the Windows shell extension is a very useful feature, but sometimes, when the user have too many installed shell extensions,
the Windows context menu may become too cluttered. In order to remove the DiskSavvy entry from the Windows context menu, open the options
dialog, select the 'General' tab and disable the Windows shell extension.
