TreeSize is a program for Windows that serves as a disk space analyzer capable of displaying the contents of a folder and subfolders inside it. It is possible to access the utility by clicking on its icon located in the system tray.

Storage space management

The software solution presents information in a clear and concise manner. As the name suggests, it portrays folders on your drive like they are branches. Each one extends in accordance with its capacity. This approach simplifies the process of understanding how space is shared.

You have the option to view utilized storage by sorting based on file size, allocation, item count, and percentage that represents overall usage. These options are readily accessible as soon as you open and navigate through the tool.

Continuing with the tree branch graphical interface, when you click on a folder, you have the option to expand and rescan. You can also exclude these directories from the storage calculations performed by the application.
