The file manager

Every folder, made to be looked at.

Thumbnails drawn from the files themselves, a panel that knows what each one is, and a player that stays out of the way. This is the real window, not a mock-up.

Built-in player

Press space. The folder plays.

Open a folder, press play. The deck follows the queue, shows every track’s tempo — read from its tags, or estimated from the audio — and keeps the level meter moving while you work.

An illustration: the artists and albums are invented, and the level meter is drawn, not listening.

Dashboard

Honest numbers, or none at all.

A local index walks your disk once and keeps itself current. Every card says where its figures came from — measured, observed or estimated — and nothing is invented to fill a gap. Tap a card to see it big.

  1. Storage over time measured

    Change needs two readings. On day one there is only one, so the card says so — in those words — instead of drawing a flat line and calling it a trend. Beside it, what could realistically be freed, by category — every row says how it knows.

  2. Your disk measured

    System, indexed and free space in one glance — plus a duplicate hunt one click away, the largest files and a day-by-day picture of what changed.

  3. What’s on it measured

    Storage by kind, the hours of the day your files were last touched, and insights written as plain sentences — never advice to delete.

  4. Where the space goes measured

    A map of folder sizes you can click into, beside how long it has been since your files last changed.

  5. Worth a look, and duplicates measured

    Stale, empty and unusually large files — and a duplicate hunt that reads bytes, not names.

  6. Growing fastest, projects measured

    The folders that took on the most new data, and the projects the index recognises — with the evidence.

measured

Counted from the index. A figure you could check yourself.

observed

Seen by the file system. Dates and activity, as macOS reports them.

inferred

Worked out, and marked. Estimates carry a tilde and never pose as counts.

Features

Built for the folder that got out of hand.

A real AppKit table underneath, so fifty thousand entries scroll the way ten do. The rest is what a file manager should have had all along.

A file list that tells you more before you open anything

Number, name, kind, size, date, tempo, duration. Click, ⇧-click and ⌘-click behave exactly as in Finder. Columns retire gracefully as the pane narrows — the name never gives way.

One queue, and an undo

Copy, move, rename and trash share a queue you can pause and cancel. Nothing is overwritten. A finished move can be taken back.

Rename as a pipeline

Nine steps, run in order. See every current name against every new one — conflicts counted — before a byte is written.

Order without moving anything

Collections gather paths from anywhere on the machine. Give one a name, a note and a cover — it reads like a record sleeve in the sidebar.

It plays what it lists

Audio and video through one engine. Tempo is trusted when tagged, analysed from the sound when not — and estimates carry a tilde.

One field over the whole window

⌘K searches actions, your library, your collections and the files in the index — at once, from the keyboard, without touching the disk on every keystroke.

Knows a repository from a project

Inside a Git repository the header shows the branch and what changed. When a folder is video, audio, photo, design or code work, a chip says so — and the inspector lists the evidence.

Duplicate hunt

Three passes, and only the last one is expensive.

It reads bytes rather than guesses — and it starts by not reading them at all. Nothing is removed for you; the group is shown, and you decide.

What leaves the machine

Nothing, unless you ask it to.

Your files never leave your Mac. The only connections are the daily update check, license activation once you buy, and — only if you choose to sign in — syncing your settings (never your files). There is no telemetry watching how you use it — the trial is the full app, not a demo.

An account is optional — and small

An email and a one-time code, no password. Only preferences follow you: theme, accent, density, dashboard cards. Paths, the index, history and collections stay here.

It says what it wasn’t allowed to read

Refuse access to a folder and the storage view lists it, rather than quietly leaving it out of the totals.

Built to stand still

0 % CPU at rest, measured in folders holding tens of thousands of files. Metadata and tempo are read only for the rows you can see.
