TreeSize

TreeSize is a disk space analysis tool developed by JAM Software. It provides users with a clear overview of how disk space is being used on their hard drives, network drives, and even cloud storage. The software scans selected drives or folders and displays their contents in a hierarchical tree view. Each folder and file is represented by a bar in the tree, with the length of the bar proportionally representing its size. This visual representation makes it easy to identify large files or folders that are consuming significant disk space.

The main interface of TreeSize presents a directory tree where the size of each folder is displayed next to its name. Users can expand and collapse folders to drill down into the file system. Beyond the basic tree view, TreeSize offers various reporting and visualization options. It can generate charts and graphs to illustrate disk space usage patterns, helping users to quickly spot trends and potential issues. The tool also allows for the search and identification of duplicate files, which can further help in reclaiming storage.

TreeSize is available in several editions, including a free version with core functionality and paid editions that offer advanced features such as network monitoring, scheduled scans, and integration with cloud storage services like OneDrive and SharePoint. It is widely used by system administrators and individuals looking to manage their storage efficiently, free up disk space, and understand their data footprint. The software supports multiple Windows versions and can also be run from a command line for scripting and automation purposes.
