Overview of TreeSize Pro

TreeSize Pro is a program for viewing where the space on our hard disk has gone. It scans the selected drive or folder and provides a detailed size breakdown of each folder, from the largest folders down to subfolders and individual files. This gives us a comprehensive overview at a glance of which file types or folders are consuming the most space, without having to manually open and check each folder one by one.

The highlight of this program is its intuitive display. Scan results are sorted by size from largest to smallest, accompanied by bars and charts that help you compare the size of each folder quickly. You can click to view the contents, see the largest files, the oldest files, or categorize them by file extension and owner. For those whose hard disk is nearly full and don't know what to delete first, this program clearly points out where to start. It is easy to use: open the program, select a drive, and wait a short moment for the scan results to begin managing your files.

In addition to viewing sizes, TreeSize Pro includes tools to find duplicate files, search for files based on specific criteria such as size, date, or filename, and scan for files that haven't been used for a long time. Furthermore, you can compare previous scan results with the current one to see where space has increased or decreased over time. Scan results can be exported as reports in various formats for record-keeping or sharing with others. It is suitable for both personal use and managing multiple computers in an office, as it supports network drive scanning and can be scheduled for automatic scans.

For those who want to keep their storage space organized, TreeSize Pro makes it much easier to identify why the disk is full. Instead of guessing or deleting files randomly, we know exactly which files are large, which are duplicates, and which folders should be handled first. This helps reclaim free space with confidence without wasting time searching manually. For junk file removal and holistic system maintenance, see CCleaner Pro Can be assembled.

What's new

  • New search path input. Add search paths in fewer steps using only the keyboard. The path selection menu displays all drives connected in Windows Explorer, along with drive letters and free space. You can select multiple drives at once, view recent search history, pin important paths, and selected paths are displayed as removable chips.
  • New selection logic for results. When searching for duplicate files or performing general file searches, you can select files to manage using rules, such as selecting only files within a specific path or only those outside of it, and create custom detailed selection rules via advanced options.
  • Chatbot JAMie Now integrated into the program. Ask questions about usage without leaving the application. JAMie cannot see your screen or access scan data.
  • Preview two files simultaneously to compare content. Open this via the pin icon in the file preview pane or the checkbox in the Ribbon. The preview pane now only appears when a file is selected, providing more space on the right.
  • Change file ownership recursively for all sub-elements in a folder in a single step, and set the detail level for SQLite exports just like other export formats.
  • New, modern-looking installation page, and improved help page for scan targets to make it easier to understand.
  • Fixed several bugs, such as special characters displaying incorrectly when importing SQLite scan files and during Excel exports on systems with the Beta Unicode UTF-8 option enabled. Fixed errors when searching file content in Google Drive and installation interruptions caused by background processes, as well as an issue where switching between MSI and standard installers resulted in duplicate app entries.
  • Fixed other minor issues, such as copying reports when batch renaming files, saving reference drives in the duplicate file deletion window, and the cursor disappearing while renaming files when text scaling is set above 120%.
