Temporary files and caches can occupy storage after an application or update has finished using them. Windows 11 can free up disk space by removing selected categories through its Storage settings.
Temporary files lists removable data with a description and size for each category. Windows can leave files that are still in use, and caches such as thumbnails can be recreated, so the selected total is an estimate rather than a guaranteed amount of recovered space.
Cleanup does not require uninstalling applications or searching system folders for files to delete. Personal files and the option to return to a previous Windows installation need particular care if their categories appear in the list; backups should be available before removing anything that may still be needed.
Steps to free up disk space in Windows:
- Press Windows + I to open Settings.
- Type Storage in Find a setting.
- Select Storage settings in the search results.
- Open Temporary files under System > Storage.
The storage scan can take a moment to populate the categories.
- Review every selected cleanup category and its size.
The selected files and their data will be permanently deleted. Do not select Downloads or Recycle Bin unless all their contents are disposable. Removing Previous Windows installation(s) removes the option to go back to that installation. Categories vary between computers.
- Click Remove files for the reviewed selection.
- Click Continue in the Remove files confirmation.
- Select Storage in the breadcrumb after cleanup finishes.
Finished temporary files cleanup indicates that the removal has ended.
- Open Temporary files again.
- Confirm that the cleaned categories are smaller or absent.
Some temporary files can remain in use or reappear. The drive's free-space figure can round away a small change; the reduced cleanup categories provide a more detailed check.
