Space Lens

Visual disk space analyzer with interactive treemap visualization.

Interactive treemap visualization showing disk usage by folder and file

Overview

Space Lens helps you understand where your disk space is going through an intuitive visual representation. Find large files and folders at a glance.

How It Works

Space Lens uses a treemap visualization where:

• Each rectangle represents a file or folder
• Rectangle size is proportional to file/folder size
• Colors indicate file types
• You can drill down into folders

Scanning Options

Quick Scan

Filters

Filter the visualization by:

• Minimum Size: Hide files smaller than threshold
• File Type: Show only specific types
• Date Modified: Find old/recent files
• Hidden Files: Show/hide dotfiles

Tips

1. Start with home folder - Most user data is here
2. Check Downloads - Often contains forgotten large files
3. Look for duplicates - Similar-sized files in different locations
4. Old iOS backups - Can be several GB each
5. Application Support - Some apps store lots of data here
