TreeSize Free at a glance
TreeSize Free (from JAM Software) is a popular Windows utility for visualizing disk usage and finding what is filling up a drive — a handy tool in the admin toolbox. It ships regular releases; it's an occasional-use utility rather than a resident service.
For admins TreeSize runs with the user's (often elevated, to scan all files) rights and is used on demand, so the update driver is features and compatibility rather than exposure. Keep a reasonably current copy and source it from the official site. New versions bring scanning and reporting improvements; the paid Professional edition adds more analysis and scheduling for those who need it. Because it's often run portable, watch for stale copies on technician sticks. Its risk profile is low, but as with any tool run elevated, get it from the vendor rather than a repackager. Patchletter surfaces new TreeSize releases.
