Check how much space is free
Open Settings, System, then Storage. Note the total and free space.
Empty the Recycle Bin carefully
Open the Recycle Bin and check it before emptying. Files are harder to recover afterwards.
Use Temporary files
In Storage settings, open Temporary files. Review each category. Do not select Downloads unless you have checked that folder.
Sort personal folders by size
Check Downloads, Videos, Pictures and Desktop. Move old large files to a checked backup: A second copy of important files stored somewhere separate from the original device. Glossary drive if you still need them.
Remove unused programs normally
Use Settings, Apps, Installed apps. Uninstall only programs you recognise and no longer use.
Check cloud files
If using cloud storage: Files stored through an internet service so they can be accessed from approved devices. Glossary, confirm important files are fully uploaded before choosing any option that removes local copies.
