View Free Disk Space and Reclaim Storage: Tips & Tools

5 Simple Ways to Check Free Disk Space on Your Computer

1. File Explorer / Finder (GUI)

   • Windows: Open File Explorer, select “This PC” — free space shown under each drive. Right-click a drive → Properties for detailed used/available breakdown.
   • macOS: Open Finder, select a drive in the sidebar or desktop, press Command-I (Get Info) or choose View → Show Status Bar to see free space.

2. Settings / System Storage overview

   • Windows Settings: Settings → System → Storage shows each drive and category breakdown with recommendations to free space.
   • macOS: Apple menu → About This Mac → Storage shows a visual bar and storage categories.

3. Command Line (cross-platform basics)

   • Windows (PowerShell): Get-PSDrive -PSProvider FileSystem or Get-Volume shows free/used space.
   • Windows (CMD): dir on a drive shows free bytes at bottom.
   • macOS / Linux (Terminal): df -h lists mounted filesystems with human-readable sizes; df -h /path for a specific path.

4. Disk Utility / Disk Management tools

   • Windows: Disk Management (diskmgmt.msc) shows partitions, sizes, and unallocated space.
   • macOS: Disk Utility shows volumes and capacity, useful for checking APFS/container usage.
   • Linux: GNOME Disks or KDE Partition Manager provide GUI views of partitions and free space.

5. Third-party tools & apps

   • Tools like WinDirStat, TreeSize, DaisyDisk, or Baobab scan drives and show a breakdown by folder/file so you can identify large items and reclaim space.

Tips: check both free space and available space (some OSes reserve space for system use), and run these checks regularly if you manage limited storage.
