TreeSize Professional is a powerful disk space analyzer that helps you manage the space of your hard drives. It lets you clearly view which folders and files take the most of the disk space, regardless of their type (format) or of their location on the drive. It detects and analyzes even files hidden underneath many subfolders. Once you are able to visualize how the disk space is consumed, you can plan and run effective file cleaning sessions that will eventually lead to gaining additional free disk space.

TreeSize Professional is a very comprehensive tool that offers a lot of handy additional functions and features, such as tree maps, detailed view mode that shows a lot of additional information for every file, various statistics and filters, lists with the largest files (“top 100 largest files”), and so on. There’s also a fully customizable file searching function that lets you quickly locate any files.

The analysis results will be displayed as parts of clear reports which can be exported to various file formats. Even if it is powerful and feature-rich, using TreeSize Professional poses no problem thanks to the intuitive and self-explanatory interface.

In conclusion, TreeSize Professional is a great tool that makes disk management simple and effective.
