Scanner (software)
Scanner is a disk space analyzing and management tool for Microsoft Windows operating systems. It displays the disk space usage of any drive or directory in the form of a multilevel pie chart which can be navigated up and down through the directory tree. When the mouse cursor is placed above a pie the program displays which directory the pie represents, how many files it contains and the overall disk space occupied by it. A context menu allows users to open the directory inside the Windows Explorer, hide and un-hide it from the diagram as well as deleting the pie from the disk either via the Recycle Bin or permanently.
