The common functionality of all editions is to determine and to display drive/folder sizes, and to create reports such as tables and charts (pie chart, bar chart or treemaps). The collected data can be exported to plain text, clipboard, HTML, XML, or Microsoft Excel formats.
The Professional and Personal Editions enable a user to search specifically for large, old, or obsolete files, e.g. temporary files, duplicates or caches of web-browsers such as Internet Explorer, Mozilla Firefox, or Opera. Duplicate files can be identified via MD5- or SHA256-checksums and duplicated or replaced by hardlinks.
The first version of TreeSize was programmed by Joachim Marder in 1996. It was designed to offer the features of Unix's du on Windows systems, with the addition of a GUI. The software tried to overcome the drawbacks of both the du command and Windows Explorer's right-click context menu. One year later, the newly founded German company JAM Software published TreeSize in a freeware and two shareware versions. Version 7.1 was released in May 2019.
In October 2012 a freeware version with a touch-optimized interface was released for Windows mobile phones, available in Windows Store.
