Disk space analysers for Windows and Mac
Where the room went and when it runs out — a map of a drive, a forecast from measurements, a triage of clutter, a report you can keep.
4 programs, free while we’re in preview. One file each. No account, no installer, nothing to uninstall.
Double-click it, pick a folder, see where your disk space actually went.
The Simple one of the 4: it keeps the settings to a minimum and picks sensible defaults for you, so there is almost nothing to learn before it is useful.
At this rate, when does /var/log fill up? A regression gives you the date.
The Vertical one of the 4: it is tuned for that work specifically, with presets and reports built around it rather than every setting under the sun.
Sorts what's eating your disk into junk types, and deletes absolutely nothing.
The Pro one of the 4: it adds the deeper settings and finer control that people who use it every day ask for, without getting in the way on a quick job.
Point it at six shares and see which one runs out of room first.
The Team one of the 4: it adds what a team needs: command-line control for scripts, settings you can roll out across machines, and a record of everything that ran.
Reading on this job
- What is filling up my hard drive? Finding the folder that grew, knowing what kind of thing grew, and knowing when the drive actually runs out are three different questions.
What all 4 of them do the same way
- Nothing is deleted. Anything a program removes is moved somewhere you can get it back from, and anything that changes files shows you the whole plan before it touches one.
- Nothing is reported back to us. No program here signs you in, phones home or counts what you did. The ones that use the network at all use it because that is the job — fetching a file you asked for, reaching a machine you named — and nowhere else.
- One file. Download it and run it. There is no installer, no runtime to fetch and nothing left behind if you delete it.
- The window and the command line are the same program. Double-click it for the window; give it arguments and the same binary runs as a command-line tool.
- The source is published for every program here, next to the download.
