DaisyDisk vs WizTree

DaisyDisk

• Mac users who keep running out of disk space
• Finding what is behind large System Data or Other storage figures
• People who want a one-time purchase that covers their personal Macs

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

DaisyDisk

• macOS only; the current version needs macOS 10.13 or newer, and the FAQ says there is no Windows or iOS version.
• The free trial cannot delete files, show them in Finder, scan as administrator or scan cloud storage, and shows purchase reminders.
• The Mac App Store edition cannot scan as administrator and only detects hidden and purgeable space without revealing or purging it.
• It does not find duplicate files, and deletion is permanent, not a move to the Trash.

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.

DaisyDisk

Sunburst disk map

Scans a disk or folder and draws its contents as a sunburst map that you browse to locate the largest files and folders.

Fast scanning

The vendor quotes 12-20 seconds for an APFS SSD startup disk and 6-12 seconds for an HFS+ one, and 3-5 minutes for NTFS, FAT and exFAT volumes.

Collector and deletion

Drag items to the Collector, review them, then click Delete, with 5 seconds to cancel. Files are removed permanently, and system folders are not accepted.

Hidden and purgeable space

Detects space that regular scanning cannot account for, reveals it by scanning as administrator, and can purge purgeable space and local snapshots.

Cloud scan

Connects Dropbox, Google Drive, Microsoft OneDrive and Box and scans them over the network like a local disk, without allocating local disk space.

Quick Look preview

Pressing Space previews any file with the built-in Quick Look, so you can identify it before deciding whether to delete it.

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.
