What is TreeSize Free?
TreeSize Free breaks down disk usage by folder and file, helping you locate the directories that occupy your storage before deciding what to remove. Its folder-size view and treemap provide two ways to explore the same space usage. You can scan local or external drives and save the displayed results as a PDF report.
This download is the portable ZIP for 64-bit Windows 10 and 11: extract it to run without installation, including from a USB drive on a home PC. The Free edition is for private, non-commercial use and does not support Windows Server. It does not include duplicate-file search, scheduled scans or command-line automation; those are paid-edition features.
What it offers
