// the problem

Installer files pile up fast

You download an app, drag it to Applications, and forget about the DMG. Weeks later there are dozens of them.
PKG and MPKG installers stick around long after the installation is done, eating disk space for no reason.
Manually hunting for .dmg and .pkg files in a cluttered Downloads folder is tedious and easy to forget.
Even if you remember to delete them, new installer files keep arriving every time you install or update software.
Installer files can range from a few MB to over a GB. Over time they waste significant storage.

// templates

Two built-in templates, one-click setup

AutoShelf includes ready-made templates for installer cleanup. Pick one, choose your folder, and you're done.

Auto-delete DMGs Moves .dmg files to the Trash the moment they appear in your Downloads folder. Covers the most common installer format on macOS.

Auto-trash Installers Trashes .dmg, .pkg, and .mpkg files. Covers all standard macOS installer formats so nothing slips through.

// how it works

Set it once. Never think about it again.

Pick a template

Choose Auto-delete DMGs or Auto-trash Installers. Both are built into AutoShelf and ready to go.

Choose your folder

Select Downloads or any other folder. AutoShelf starts watching immediately.

Forget about it

Every .dmg, .pkg, or .mpkg file gets trashed instantly. No alerts, no drag-and-drop, no manual cleanup.

// more options

Go beyond the basics

Custom file extensions

Create rules for any extension: .zip, .rar, .7z, .exe, .app, or anything else. AutoShelf matches by extension, not just templates.

Delay before action

Set a delay so files are only trashed after a few seconds or minutes. Useful if you need to open the DMG before it disappears.

Confirm before trashing

Enable confirmation to review each file before it gets sent to the Trash. You stay in control while AutoShelf handles the routine.

Move instead of trash

Prefer to keep installer files in an archive folder instead of deleting them? Create a rule that moves them to a designated folder instead.
