DaisyDisk Alternative for Windows

Why There Is No DaisyDisk for Windows

DaisyDisk is a macOS application and has been for its whole life. There's no Windows build, no beta, and no announced plan for one. If you have moved to a PC, or you run a Mac at home and Windows at work, the thing you are missing is not the app itself. It's the picture it draws.

What You Actually Miss: The Sunburst

Most disk tools hand you a sorted table. That answers "what is the single biggest file" and almost nothing else. A sunburst answers a better question: where is the weight of my disk, and which branch is it hiding in.

Each ring is one level deeper in your folder tree, and every wedge is sized by the space it occupies. A folder that is quietly 60 GB is a fat wedge you can't miss, even when it is buried six levels down with an unremarkable name. You read the whole drive in one glance instead of expanding folders one at a time hoping to stumble onto the problem.

The Usual Windows Suggestions, and Why They Fall Short

Search for a replacement and you'll be pointed at the same few answers. They are all good tools, some of them free, and none of them draw what DaisyDisk drew.

• WinDirStat, WizTree and SpaceSniffer draw a treemap, a grid of nested rectangles. WinDirStat was revived in 2024 and, like WizTree, now reads the NTFS index directly, so both are quick. A treemap is a genuine visualization, but rectangle area is hard to compare by eye, and deep folder structures turn into confetti. Our WinDirStat alternatives guide compares them in detail.
• TreeSize leads with a sortable table and puts the charts second. The free edition is for personal use and leaves out duplicate search, and the paid editions are priced per user per year, with perpetual licenses also on offer.
• Windows Storage settings gives you broad buckets like Apps, Temporary Files, and Other. "Other" routinely hides tens of gigabytes with no way to drill in.

LumaDisk: The Sunburst, Built for Windows

LumaDisk renders your whole drive as an interactive sunburst chart, the same way DaisyDisk does on the Mac, and it draws the map while the scan is still running rather than after it. Click a wedge to zoom into that subtree, follow the breadcrumb back out, and reveal anything in File Explorer, or queue it into LumaDisk's own Bin and reclaim it without leaving the app. Reclaiming deletes for good rather than moving anything to the Recycle Bin, so you get a ten-second window to undo instead, and system folders can never be queued at all. If a treemap reads better for a particular drive, one click switches the view and the choice sticks.

It's a native application built with Rust and GPUI, the same GPU-accelerated stack behind the Zed editor. There's no Electron, and it runs natively on both x86-64 and Windows ARM64, so the chart stays smooth while you drag through a drive with a million files on it.

On NTFS drives it also offers a one-click Fast Scan that reads the drive index directly instead of walking every folder, after one administrator prompt per session. Large local disks map in seconds rather than minutes.

For Developer Machines

This is where a PC dev box diverges sharply from the average laptop. Your biggest reclaimable folders are almost never photos or videos. They are build output you can regenerate at any time, scattered across every project you've ever cloned.

LumaDisk detects and groups them for you instead of leaving you to recognise them wedge by wedge: node_modules, .next, target, .gradle, and other regenerable build directories get collected into a single reclaimable total you can act on in one pass.

On a machine with a few dozen repositories on it, that number is routinely 10 to 50 GB. Every one of those folders comes back on your next build, which makes them the safest gigabytes on the whole disk to delete.

Duplicates

The other quiet consumer is files you already have somewhere else. ISO images, installers, video exports, and project archives get copied to a second folder "just for now" and then live there forever. LumaDisk surfaces duplicate copies alongside the sunburst, so you can keep one and drop the rest.

Because you're looking at the real file and its real path before anything happens, you're never deleting on trust. You can see which copy sits in a working directory and which one is the stray in Downloads.

What It Costs

LumaDisk is free to install from the Microsoft Store and includes a 7-day trial of everything. After that, scanning and the sunburst stay free for good, and a one-time purchase unlocks the rest. There's no subscription.

For reference, DaisyDisk is a one-time purchase too ($9.99 on the Mac), which is a large part of why people liked it. The pricing to watch for on Windows is per-year licensing, where you pay again every year for the same feature set.

If You Use Both Mac and Windows

LumaDisk ships on macOS as well, with the same sunburst and the same build-cache detection. If you're moving between a Mac and a PC, you get one tool and one mental model on both, rather than learning a treemap on one machine and a sunburst on the other. On the Mac side, our DaisyDisk alternatives for Mac guide covers the free options too.

You should not have to pay twice for the same app. A license bought on lumadisk.com covers up to 3 devices, in any mix of Macs and Windows PCs: email support and we'll send you a Microsoft Store code for each PC. Bought on the Microsoft Store and want the Mac build as well? Email support and we'll send you a macOS code.
