How do I free up space on my computer?

Large downloads, unused apps, old installers, and an unemptied recycle bin are safer starting points than system folders.

Start with large downloads, unused apps, and the recycle bin; leave system folders alone unless you know what they contain.

Why a full drive slows everything down

Your computer uses spare disk space as working room — for updates, temporary files, and everyday breathing space. When the drive is nearly full, everything gets slower and updates start failing. The good news: most of anyone’s disk is usually a handful of huge files, not thousands of small ones, so the fix is faster than you would think.

What to do, step by step

1. Look at the map first. On Windows: Settings, System, Storage. On a Mac: System Settings, General, Storage. Both show what is actually eating the space.
2. Sort your Downloads folder by size and delete old installers, duplicate videos, and disk images you no longer need.
3. Uninstall apps and games you have not opened in months — they are usually the second-biggest pile.
4. Empty the Recycle Bin or Trash. Until you do, “deleted” files are still sitting on the drive taking up room.
5. Move the keepers — photo libraries, videos, old documents — to an external drive or cloud storage instead of deleting memories.
6. Turn on the built-in housekeeper: Storage Sense on Windows, or follow the storage recommendations on a Mac, so clutter does not quietly rebuild.
