TreeSize Professional is a powerful and flexible harddisk space manager for Windows 200X / XP / Vista (32 and 64 Bit). Find out which folders are the largest on your drives and recover megabytes on your disks. TreeSize Professional shows you the size, allocated and wasted space, the number of files, 3D charts, the last access date, the file owner and permissions, the NTFS compression rate and much more information of several folders or drives you choose. It also lets you search drives, entire servers or the entire network for old, big, temporary and duplicate files.

File Search: While calculating MD5 checksums, the duplicate file search now shows the number of remaining files in the status bar.
File Search: The "Duplicate Files" result list now shows the number of files and their summarized size in the status bar, and no longer the number and size of file groups.
File Search: If more than one file is selected, the number and size of the selected files is shown in the status bar.

Bugfix: File Search: A problem has been fixed when using the "Move Checked" function for complete folders that were moved to a ZIP-File.
