Mika+FileScope

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.

Features

• 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.
• Breakdown by file type: A sortable table of every extension with file count, total size and share of the whole.
• 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.
• Duplicate finder: Files are grouped by size first, then hashed with SHA-256 in 1 MB chunks. You get the number of copies and the space you could recover.
• 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.
