Why TreeSize Professional:

Manage disk space and scan your hard disks

Find out which folders are the largest on your drives and recover precious disk space. Use TreeSize as a hard disk cleanup tool: find space hogs and remove them. Graphical analyses provide a quick visualization of disk space usage. TreeSize Professional shows you folder size and allocated disk space as well as owner and permissions, the last access date, the NTFS compression rate, and much more information for selected folders or drives.

Search for Redundant Files

The integrated versatile file search helps you find old, big, temporary, and duplicate files on drives, entire servers or the entire network. Search results can be moved, deleted or exported to a ZIP file.

Print, Export, or Compare Results

You can print detailed reports and charts or export the collected data to many different formats such as XML, XLS, TXT, CSV and many more. Compare XML reports or take shapshots of your disk space usage to track its development over time.

The application has an intuitive Explorer-like user interface and supports drag and drop operations. It is fast, multi-threaded, and supports Unicode- and NTFS-specific features. TreeSize Professional can be started from the context menu of every folder or drive.
