JAM Software TreeSize Professional v5.5.1.780

TreeSize Professional is a powerful and flexible harddisk space
manager for Windows 98/ME/NT/2000/XP/2003. Find out which folders
are the largest on your drives and recover megabytes of disk
space. TreeSize Professional shows you the size, allocated and
wasted space, the number of files, 3D bar and pie charts, the last
access date, the file owner, the NTFS compression rate and much
more information for several folders or drives you choose.
It also helps you to clean up old, big and temporary files. The
application has an intuitive Explorer-like user interface and it
is fast and multithreaded. You can print detailed reports or
export the collected Data to Excel and to an HTML, XML or ASCII
file. TreeSize Pro can be started from the context menu of every
folder or drive.
