Reclaim Disk Space: A Tidy-Up Routine for Windows

Updated November 7, 2026 · Written by the DefensiveInfo editorial team

A drive that is nearly full makes Windows sluggish and can make updates fail. A simple routine gets you out of trouble.

Look before you delete

Open Settings, then System, then Storage. Windows breaks down space into apps, temporary files, documents and more. Click a category for detail so that you target the biggest items first.

Quick wins

  • Temporary files: choose Temporary files in Storage and remove items like old downloads cache and thumbnails.
  • Recycle Bin: it still counts against your drive until you empty it.
  • Downloads folder: installers and zip files tend to pile up here.

Automate it

Turn on Storage Sense in the same settings page. It clears temporary files and the Recycle Bin on a schedule that you pick.

Apps and games

Open Settings, then Apps, then Installed apps, and sort by size. Large games and creative tools are often the main culprits. Uninstall what you do not use. You can reinstall later.

Photos and videos

Media is usually the largest personal data. Move older material to an external drive or cloud storage, and make sure a second copy exists before removing the original.

Find duplicates and giants

Use File Explorer's search with the filter size:gigantic to list very large files, and review them one by one.

Never remove these by hand

Files inside the Windows folder or Program Files should only be removed with proper uninstallers. Deleting them manually can break the system.

A healthy target

Keep roughly one fifth of your main drive free. That gives Windows room for updates, temporary work and the paging file.
