Recursive folder scan
Drop a folder on the window or pick one from the toolbar. Scanning runs in the background, so the window stays responsive even on large directories.
Native macOS utility · Free · Open source
Find out what's actually
filling your disk.
Mika+FileScope scans any folder on your Mac and groups every file by type — then shows you where the space went as a sortable table, charts, an age timeline and a duplicate finder.
Everything stays local
No account, no analytics, no telemetry. The app itself makes no network requests — the only connection it opens is the check for updates.
It never deletes anything
The duplicate finder reports what it found and reveals each copy in Finder. What happens to those files stays your decision.
Open source
Written in Swift 6 with SwiftUI and Swift Charts. Read every line on GitHub, or build it yourself in two commands.
What it does
Eight ways to look at a folder — all from a single scan.
Breakdown by file type
A sortable table of every extension with file count, total size and share of the whole — so the one type eating 98% of the folder is impossible to miss.
Charts
A donut for size distribution and a horizontal bar chart for the largest types — top eight plus a combined “Other”, drawn with Swift Charts.
Age timeline
How much of the folder is recent and how much has just been sitting there: Today, Past Week, Past Month, Past 3 Months, Past Year, Older — by count and by size.
Duplicate finder
Files are grouped by size first, then hashed with SHA-256 in 1 MB chunks. You get the number of copies, the space you could recover, and Reveal in Finder for every single one.
Category filter
Narrow everything down to Images, Documents, Videos, Audio, Code, Archives or Other. Table, charts, summary and export all follow the filter.
CSV & JSON export
Save the breakdown as CSV with human-readable sizes and percentages, or as JSON including the folder path, a timestamp and the totals.
Menubar quick scan
Turn on the menubar icon and keep a compact summary one click away — totals plus the top five file types, without the main window.
Also included: hidden-files toggle · drag-and-drop · full Dark and Light mode · Sparkle auto-updates · rescan in one click
Every view, from one scan
Real screenshots — no mockups.
Three steps
-
1
Drop a folder
Drag it onto the window or pick it from the toolbar. The scan walks the folder recursively while you keep using the app.
-
2
Read the breakdown
Switch between the table, the charts and the timeline. Filter by category when you want to look at one kind of file only.
-
3
Export or clean up
Save the numbers as CSV or JSON, or run the duplicate finder and review the copies in Finder.
Install
Download the DMG and drag Mika+FileScope into your Applications folder.

First launch takes one extra click
The app is signed ad-hoc rather than with a paid Apple Developer ID, so it is not notarized. macOS will refuse the first double-click and warn that it cannot verify the developer. To open it anyway:
- Right-click Mika+FileScope in Applications and choose Open, then confirm with Open.
- Or go to System Settings → Privacy & Security and click Open Anyway next to the blocked-app notice.
You only have to do this once. If you would rather not, build it from source instead — the result is identical.
