Get DrivePulse
Double-click it, pick a folder, see where your disk space actually went.
The Mac button is for Apple Silicon. On an older Intel Mac, get this one instead.
One file, both ways. Double-click it for the window. Run the same file from a command prompt with arguments and it behaves as the command-line tool, because the engine is inside it. Nothing else to download and nothing to keep beside it.
Early preview. The window has been built and run, but not yet on a real Windows PC or Mac, so expect rough edges. The engine underneath it is fully tested.
- One file — no installer
- Runs on your machine, offline
- Source code published below
Free while in preview. It isn’t signed yet, so Windows or macOS will ask you to confirm the first time you open it. At launch, DrivePulse is included in every plan along with the rest of the range.
You don’t need a command prompt
Double-click DrivePulse and it opens, explains what it does, and asks which folder to look at. Press Enter and it takes your Pictures folder, falling back to Downloads and then your home folder. You can drag a folder from Explorer onto the window to paste its path. When the scan finishes it waits for you to press Enter before closing, so the results stay on screen instead of vanishing.
What comes back
Three lists. Which sub-folders are eating the space, with percentages. The largest individual files, biggest first. And files that share an exact byte size.
About that third list
Same size is not the same file. Two 4.2 MB photos can be completely different pictures. DrivePulse calls them candidates and means it. Run DupePilot over them if you want the bytes genuinely compared before you delete anything.
What it won’t do
It only reads. Nothing is moved, renamed or deleted. It also can’t tell you whether your drive is failing: SMART telemetry needs hardware access this cross-platform build doesn’t attempt, so nothing in the output claims to know.
There’s a command line too, drivepulse scan <dir> --depth 3 --top 20 --json, and scripts and pipes behave exactly as they always did.
Reading on the job itself
- What is filling up my hard drive? Map the tree by size, biggest folder first, and stop descending when a branch is small. That finds the room...
Advanced & technical details Command-line builds, source code, checksums and a recorded session — for developers and IT teams
A working CLI prototype of the space-map engine: folder-level space map, largest-file finder, and duplicate-size candidate hints. SMART/disk-health telemetry needs OS-specific access this cross-platform build doesn't attempt — see the roadmap.
Naming status
Working name only — brand verdict **RENAME** (High). Collision: DrivePulse / Driver Pulse apps. Use a coined storage/device name instead.
What it draws on
Existing paid software whose best ideas shaped this program: TreeSize Professional, Hard Disk Sentinel Professional, WizTree Enterprise, CCleaner Professional.
Command line
There is nothing extra to install. The program you download is the command-line tool as well: give it arguments instead of double-clicking it and it runs as one, with its output on your terminal. The standalone builds below are the same engine on its own, for machines where you would rather not ship a window at all.
DrivePulse — instant space map for a directory tree
Usage:
drivepulse scan <dir> [--depth N] [--top N] [--json]
--depth N how many levels deep the space map groups folders (default 2)
--top N how many rows to show per section (default 10)Recorded from the shipped binary, not written by hand.
