# WizTree

> Fast disk space analyzer for Windows and macOS

WizTree is a disk space analyzer from Antibody Software for Windows and, as WizTreeMac, for macOS. It scans a drive and shows which files and folders use the most space in a tree view, a visual treemap and a list of the largest files, and it can find duplicate files and export file data to CSV. It is free for personal use; commercial use needs a supporter code priced by the size of the organization.

## Key features

- **Direct MFT scanning on Windows:** On NTFS drives the Windows version reads the Master File Table straight from the disk, which needs administrator rights, and falls back to standard scanning elsewhere.
- **Visual treemap:** Draws every file and folder as a block sized by the space it takes, so large files and large collections of small files can be spotted at a glance.
- **Largest and duplicate files:** File View lists every file and folder in order of size. Duplicates are found by name, size and optionally date, and shown under the file they match.
- **File search:** A search filter in File View finds files by name or type, with wildcard searches such as *.mp3 and regular expressions.
- **CSV export and import:** All or selected file data can be exported to a CSV file or copied to the clipboard, and exported CSV files can be imported again to track changes over time.
- **Command line:** CSV exports and MFT dumps can be run with command-line parameters, which the vendor suggests for automated auditing of drives.

## Good for

- Finding what is filling up a Windows or Mac drive
- IT staff auditing drives with CSV exports and command-line scans
- Home users, since personal use is free

## Worth knowing

- The free version is for personal use only; commercial use needs a supporter code priced by the organization's total staff, per site.
- A supporter code covers versions released within one year of purchase. Newer versions need a new code, offered at 50% off.
- WizTreeMac needs macOS 12 or later, has no equivalent of the Windows MFT scan and cannot yet scan MTP devices such as Android phones.
- The free version shows a Donate button, adds a donation message to exports and comes with no support.
