Completely Remove Apps: The Smart Uninstaller Guide

The Problem with Dragging to Trash

When you drag an app to the Trash, you're only removing part of it. Applications leave behind:

Preference files in ~/Library/Preferences
Application support in ~/Library/Application Support
Caches in ~/Library/Caches
Saved states in ~/Library/Saved Application State
Containers in ~/Library/Containers
Login items and launch agents

These leftovers can consume gigabytes of storage over time.

How Much Space is Wasted?

Common apps and their typical leftover sizes:

Adobe Creative Cloud - 2-10 GB
Microsoft Office - 1-3 GB
Xcode - 5-50 GB (with caches)
Games - 500 MB - 5 GB each
Development tools - 1-10 GB each
