BleachBit vs WizTree

BleachBit

• Windows and Linux users who want to free disk space at no cost
• People clearing browser history, cookies and app traces in one pass
• Administrators who script cleanup across many machines

WizTree

• 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

BleachBit

• There is no regular macOS version: the download page lists Mac OS X support as experimental with limited features.
• The current Windows installer is for Windows 10 and 11; Windows XP, Vista, 7 and 8 need the older 4.7.0 release.
• Importing winapp2.ini, which adds thousands of extra cleaners, is available on Windows only.
• New versions are not installed automatically; the app can notify you, and updates are downloaded from the website by hand.

WizTree

• 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.

BleachBit

Junk and cache cleaning

Removes temporary files, browser caches, logs and other junk, using built-in cleaners for Google Chrome, Edge, Firefox, VLC, system logs and many other targets.

Privacy cleaning

Erases browsing history, cookies, saved passwords and application traces across several browsers in one step. A cookie manager for keeping chosen cookies is new in the 5.1.0 beta.

Preview before deleting

You tick the items to clean, click preview to see every file that would be removed, and then delete only what you want.

Shredding and free-space wiping

Shreds sensitive files so their contents cannot be read, and overwrites free disk space to hide files that were deleted earlier.

Command line and custom cleaners

A command line interface supports scripting and automation, advanced users can write cleaners in CleanerML, and Windows users can import winapp2.ini for thousands more.

Linux system cleaners

On Linux it can clear memory and swap, delete unused localizations and broken shortcuts, and clean the APT, Pacman, Snap, Yum and DNF package managers.

WizTree

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.
