Every folder, with its real size

When your Mac says its disk is nearly full, the first question is where the space went. ZincFiles answers it as you browse: every folder in the list shows its real size, measured live, so the big ones stand out at a glance. You don't have to open a folder's info window or turn on a setting first.

Disk Usage: a map of any folder

Open Disk Usage for any folder, from your Home folder down to a single project, and ZincFiles draws it as a map where each block's area matches its size. Movies, a forgotten download folder or an old project archive show up as the biggest blocks straight away, which is far quicker than reading through a list of numbers.

Like every command, Disk Usage is one search away in the command palette (⌘K).

Large Files and Duplicates

Two places in the sidebar, under Insights, do the searching for you:

  • Large Files lists your biggest files, so you can see what's worth clearing.
  • Duplicates finds copies of the same file, so you can keep one and clear the rest.

You decide what goes

ZincFiles shows you what's taking up space; it doesn't remove anything on its own. Preview a file with Space before you decide, Quick Look-style, including archives listed without extracting them, then delete, move or archive it yourself. With dual pane you can move big folders to an external drive in one step.

See sizes everywhere with Full Disk Access

macOS protects some places, like Library and other apps' data. Give ZincFiles Full Disk Access, with one switch in System Settings, and it can show folder sizes everywhere instead of asking for permission folder by folder. It's optional, and nothing it reads ever leaves your Mac: there's no account, no analytics and no tracking. Read the Privacy Policy.
