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

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 10min that they had over 20.000 excels hidden in their networkshare.

The simplicity and speed is just awesome!

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!

FAQs

How can I find out what’s using all my disk space?

You can use a disk space analyzer to scan your storage and visually break down which folders and files are taking up the most space. These tools help you identify space hogs quickly.
With TreeSize, you can scan entire drives or specific directories and see a real-time folder tree sorted by size. It even lets you drill down to file-level details and provides bar charts for better insights.

 

What’s the best way to clean up storage on Windows?

To clean up disk space, start by analyzing what’s consuming storage—like large files, duplicates, or outdated backups. Then selectively delete what you don’t need. TreeSize makes this process simple by allowing you to sort files by size, age, or file type. It also includes filters and allows direct deletion within the interface, streamlining the cleanup process.

 

How do professionals manage disk space across multiple computers or servers?

IT teams often need centralized tools that can scan across network shares and generate automated reports. TreeSize Professional supports scanning of network drives, UNC paths, and Windows servers. You can schedule scans, export reports in various formats (like HTML, XML, and PDF), and even integrate it into scripts via command-line options.

 

What types of visual reports help with analyzing disk usage?

Effective disk analysis tools provide visuals like folder trees, pie charts, or treemaps to show data usage at a glance. TreeSize offers a structured folder view, bar charts, and customizable report exports. It highlights large folders and lets you see file types grouped by extension (e.g., videos, documents, system files).

 

Can I automatically monitor disk usage over time?

Yes, many tools allow scheduled scans and report generation to help track how storage usage changes over time. TreeSize Professional includes scheduling features where you can set regular scans, generate comparative reports, and receive alerts if certain thresholds are exceeded. This is particularly useful for monitoring growth on file servers.

 

How do I scan an external or USB drive for space-hogging files?

Most disk analyzers allow you to select any connected drive and run a scan. TreeSize detects all connected volumes automatically, including USB drives, SD cards, and external SSDs. Just select the drive from the start screen and begin your scan—it supports both NTFS and exFAT formats.
