How to use Aster.
From your first scan to a considered cleanup. Watch the 78-second walkthrough.
- 01
Install and open.
Download the DMG, open it and drag Aster to Applications. Launch Aster from there. No account or license key needed.
- 02
Choose what to scan.
Click Scan folder, select a folder and confirm. Explore the storage map; larger blocks use more space. Double-click a folder to look inside.
- 03
Find and inspect.
Open Large files. Sort by Largest first, filter by size or search a name or path. Select an item, check its location and choose Add to cleanup.
- 04
Review before you act.
Open Cleanup and remove anything you want to keep from the queue. Choose Review for Trash, check the exact paths, then continue and confirm only the items you want to move.
Aster never empties Trash automatically. Moving files to Trash does not reclaim their space until you empty it yourself. Scan access depends on your macOS permissions.

That finished video. An old installer. The archive you saved “just in case.” Find large files by name and size, without digging through every folder.

Give growing caches
a closer look.
Development leaves a trail. Aster discovers supported app caches, logs and developer caches when they’re present.
Understand what’s there before acting. A cache can still be useful—cleanup is always a decision to review.

DESIGNED AROUND YOUR DECISIONS
You choose. Aster asks.
Then it moves.
Review your selection before anything moves. Aster sends confirmed items to macOS Trash and never empties it automatically.
- Select items
- Review exact paths
- Confirm
- Move to Trash
Moving files to Trash does not immediately reclaim their disk space. You control when Trash is emptied.
Possible leftovers are suggestions to review. Some apps require their own uninstallers.
Is Aster completely free?
Yes. This release includes all features for free: storage scans, maps, large-file search, full file paths, Finder actions, app and cache discovery, and reviewed cleanup to Trash. You do not need an account or a license key.
Does Aster delete files automatically?
No. You select items, review them and confirm before Aster moves them to macOS Trash. Aster never empties Trash automatically. Some apps need their own uninstallers, and possible leftovers always deserve a closer look.
Does my file information leave my Mac?
File names, paths and scan results stay on your Mac. This free release does not require an account or contact a licensing service. Read the privacy policy for more detail.
Will Aster access every folder?
Access depends on the permissions you grant in macOS. Some locations may require Full Disk Access. Aster doesn’t bypass macOS protections, and a scan may skip locations it can’t access.
Which Macs are supported?
Aster supports Macs running macOS 14 or later. The same download includes both Intel and Apple Silicon support; macOS automatically runs the right version for your Mac.
How do I install Aster?
Download the DMG, open it, and drag Aster into Applications. Then open Aster from Applications. Version 0.4.1 is signed with Developer ID and notarized by Apple.
