Space Wizard
See where your storage actually went. Then reclaim it.
A cross-platform desktop file manager with visual drive analytics and built-in duplicate detection. See your storage as a treemap, find the folders that grew without you noticing, and manage files across drives — all without a cloud account or any network calls.
Available on
- Windows10 / 11 / Server
- macOS12 Monterey+
- LinuxDebian / RPM / AppImage
What it does.
Storage as a treemap. Click to drill in.
An interactive treemap shows your drive at a glance — file sizes scaled proportionally, colour-coded by category, drillable by folder. The 80GB folder you forgot about becomes immediately visible, which usually leads to the first reclaim of the day. Useful when shared drives mysteriously fill up at 2am and you need to know why.
- Interactive treemap, drillable by folder
- Category colouring (media, docs, code, archives)
- Sortable file lists with size and date columns
- Per-folder size totals updated as you browse
- Snapshot comparison: see what grew between two scans
Find duplicates without opening a separate tool.
MD5 fingerprinting and fuzzy name matching, integrated into the file browser. Spot duplicates in the directory you're currently viewing, or scan an entire drive. Backed by the same engine as DuplicateDuster, surfaced in a lighter-weight UI for everyday cleanup rather than scheduled enterprise sweeps.
- MD5 + fuzzy filename matching
- Per-folder scans or whole-drive sweeps
- Inline duplicate badge in the file list
- Bulk-select duplicates from the list view
- Side-by-side comparison before any delete
Same UI on Windows, macOS, and Linux.
Keyboard-first navigation, tab support, dual-pane view, breadcrumb path bar. Built on Electron so the interface is identical across operating systems — useful for teams who use mixed environments and don't want to re-learn keyboard shortcuts every time they switch machines.
- Tabs and dual-pane support
- Keyboard navigation and quick search
- Network-mapped drive discovery (SMB, NFS, mapped drives)
- Consistent UI on Win / Mac / Linux
- Per-machine remembered preferences and shortcuts
Everything else it does.
Live size monitor
Watch how much space each folder is using update in real time as files are created, deleted or modified.
Archive on the spot
ZIP entire folders or selections without leaving the file manager — useful for export, transfer or quick cleanup.
Per-user preferences
Default view, hidden-file toggle, column visibility, keyboard shortcuts — all configurable and remembered per machine.
Zero cloud
No accounts, no sync service, no background telemetry. The app is allowed to be offline and stay useful.
