## Where the space goes

### System Data

caches, logs, snapshots, temp files. Hidden system folders that won't explain themselves.

### Build caches

Visual Studio, Gradle, old installers. Every build leaves gigabytes behind. Safe to clear once reviewed.

### Docker disk image

Docker Desktop VHDX. One virtual disk file that can quietly grow to tens of gigabytes.

### node_modules

one in every repo you've cloned. Hundreds of copies across old projects. Find them in one scan.

### Duplicate files

photos, videos, downloads. Same file, multiple copies. Keep the keeper and delete the rest.

### Uninstall leftovers

AppData and ProgramData. Uninstalling an app often leaves residual caches and telemetry.

## Scan. See. Clear.

### Storage map

Scan a full PC, a user profile, or any folder. Explore a treemap sized by disk usage, inspect files, and review selected items in Cleanup Queue before removing them.

### Applications

Browse installed apps with measured sizes. For supported apps, launch the Windows or vendor uninstaller and choose whether to keep app data or review leftovers.

### Duplicates

Find identical files with three-pass content hashing. Choose a copy to keep, then review the redundant copies in Cleanup Queue.

### Snapshots

Save a scan snapshot and compare earlier and later scans of the same location.

### Live monitor

Watch CPU usage, memory pressure, network rates, and free volume space.

## Eight views

- **Folders.** Browse folder cards with their sizes and item counts, then open a folder to explore deeper.
- **Sunburst.** Rings radiating from the scan root so nested weight is obvious at a glance.
- **Flame.** Follow stacked folder levels, with wider blocks showing where more disk space is used.
- **Bubbles.** Compare relative sizes with nested circles. Large circles make the biggest items stand out.
- **Mind Map.** Follow branches from your scan root, with dots and links showing relative storage weight.
- **Top Sizes.** The biggest items, ranked. Skip the hunt and start with the worst offenders.
- **Age Map.** Group storage by last-modified date and review large, older files. Age reflects modification, not last access.
- **Treemap.** See nested files and folders as rectangles sized by disk usage. Select a block to inspect it.

## Questions

### Is ScanMyDisk available for Windows?

Yes. ScanMyDisk is currently available for Windows 10 and Windows 11.

### Is ScanMyDisk available for macOS?

The macOS version of ScanMyDisk is currently in development and coming soon.

### What does ScanMyDisk do?

ScanMyDisk helps users visualize disk usage, identify large files and folders, find duplicates, inspect storage-heavy files and understand what is consuming disk space.

### Does ScanMyDisk upload my files?

No. Disk scanning and analysis are designed to run locally on the user’s device.

### What does Scan My Disk actually do?

It scans a drive or folder and maps every byte, then gives you eight ways to look at the result — folders, sunburst, flame, bubbles, mind map, top sizes, age map and treemap. From there you can find duplicates, compare saved scans, run a cleanup preset, uninstall leftovers, or stage files for review.

### Do I need an account?

No. Buy a lifetime licence and the key shows on the next screen. Install the Windows app and paste the key on first launch.

### How many PCs can I use?

One PC at a time. Deactivate on the first machine, then activate on the next. Fourteen days offline grace if you forget.

### Is my data uploaded?

No. Scanning, hashing, and duplicate matching all run locally on your PC. File names never leave the machine.

### What if I want a refund?

15-day money-back guarantee. Email support@scanmydisk.com.
