How to clean up your Downloads folder on Mac

A practical guide from the makers of Clear Storage — Disk Visualizer

The Downloads folder has a one-way door: files arrive constantly and almost nothing ever leaves. The biggest offenders are files whose job ended minutes after they arrived — app installers you already installed, archives you already extracted.

What's actually safe to delete

• DMG files: disk images used to install Mac apps. Once the app is in your Applications folder, the DMG has no further purpose. Safe to remove.
• PKG files: installer packages — same story. After installation they're dead weight.
• ZIP archives: if you extracted the contents, the archive is redundant. If you never extracted it, decide whether you still want what's inside.
• Images and videos: often already saved elsewhere (Photos, a project folder) — these need a quick look rather than blind deletion.

The scan-and-review workflow

1. In Clear Storage, run a scan that includes your Downloads folder. The Downloads results surface old DMG installers, PKG files, ZIP archives, images and videos, with sizes and dates.
2. Sort by size. Installers for big apps routinely sit at 1–4 GB each; a few of them is a fast win.
3. Check dates. A DMG from a year ago has been installed or abandoned either way.
4. Select, review once more, clean up. The freed space is logged in the app's history.

Keeping it clean

Two habits prevent the refill: delete the installer immediately after installing an app (make it part of the same motion), and rescan Downloads once a month — the app's menu bar icon showing current disk usage is a good reminder that it's time.
