TreeSize Professionalv7.1The powerful disk space management software


Main Window

The main window offers a clear and easy to use interface which is split into the file system tree on the left and the details view on the right. An optional bar chart facilitates easy overview. While the scan is performed you can already browse through the constantly updating results list. Of course TreeSize supports Unicode file- and directory names.

Details View

In the "Details" view you will find a lot of valuable information about the disk usage like the folder size, the disk space wasted due to the file system structure, the last access date, the NTFS compression rate and the owner. The list can be sorted by any column, additional columns can easily be added using the context menu.

Tree Map (2D/3D)

The tree map is an hierarchical chart visualizing the size of all subfolders (not only the direct child folder) of a selected directory branch. The tiles can be viewed in 2D (pictured) and 3D mode.

Pie Chart/<br />Bar chart

The pie chart and bar chart provide a quick overview over the disk space usage. The charts can be printed or copied to the clipboard, the toolbar offers visualisation options.

File Search

The TreeSize file search helps you to find obsolete and very large files. The particular search types can be configured in detail and certain files or folders can be easily excluded from the search results - for instance recently changed files.

Duplicate Search

Duplicate files waste hard disk space. TreeSize provides a specialized duplicate search and enables you to deduplicate files. You can easily delete or move duplicate files or replace them with NTFS hardlinks.

File Extensions

The used disk space can be broken down into file types. Filtering the file system tree on the left by certain file extensions will make it easy to find folders containing many of the particular file types.


Used disk space can also be grouped and filtered by users. This way you can easily see which user accounts occupy the most disk space.

File Age

TreeSize enables you to sort files by file age. Intervals can be configured for "creation date" , "last change" and "last access".

Top 100 Files

The Top 100 pane provides an overview about the 100 largest files found during the last scan.

Configure TreeSize

Many aspects of TreeSize can be configured in the options dialog, e.g. the view, the export of data or startup options.

Compare Reports

TreeSize enables you to save file system branch information to an XML file or to take a snapshot of the disk space usage at a certain point in time. To monitor disk space usage development you can compare the results of different measurements.

Schedule Tasks

In the Professional Edition "Schedule Tasks" dialog you can now add customized TreeSize Tasks to the Windows Scheduled Tasks.
Please note: This feature is available in the Professional Edition only.
