Visual Tour

The pie chart of TreeSize allows you to overview the most important data on disk space usage at one glance.

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 chart facilitates easy overview. 

The treemap chart is a 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.

The Details view presents you a lot of valuable information about the disk usage like the folder size, the disk space wasted by the file system structure, the last access date, the NTFS compression rate and the owner.

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

The top 100 panel provides an overview about the 100 largest files found during the last scan.

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.

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

What Our Customers Say

I LOVE the product and we use it daily for not only reporting but for administering our CIFS environment. *Honestly I'm probably doing more with the product than you intended but it has been a life-saver for my department.

Shelly Birkla, Storage Services, University of Notre Dame

Thank you for the ongoing support for TreeSize. Just yesterday I was able to demonstrate that a certain action of just manually updating a set of excel files would be a near impossible task since I was able to show them in less than 10 min that they had over 20.000 excels hidden in their networkshare.

The simplicity and speed is just awsome!

Manfred De Jong, Manfred De Jong Consultancy

Very glad I bought the software yesterday! I've seen my software company's support staff use Treesize. I'm personally always pretty hesitant about purchasing software. But after trying out the trial... MAN! It's night and day difference when compared to Windirstat.

The speed difference alone is incredible!

Thibault Molleman, Molleman De Coster BVBA

I've just tried a scan on a large bucket and it reported the results far quicker than I can get the results directly from the aws console!! Great work!! Amazing.

I remain super impressed with your work, thanks loads.

Charlie Daffarn, Omnicom Group IT | paige

TreeSize Professional from JAM Software is the most powerful program I’ve seen for analyzing how disk space is being used. My local hard drive, which is partitioned as a main C: partition and a supplementary D: partition, has almost 450,000 files using 665GB. The scan completed in 37 seconds!
