    I kept getting low disk space warnings even after emptying the Recycle Bin. It turns out Windows hides huge app caches and log files. CleanMate showed me exactly what was taking up space and cleaned it in seconds.

1. Settings > System > Storage > Temporary files

Select safe items like Temporary files, Recycle Bin, Windows Update Cleanup, Thumbnails, and Delivery Optimization Files. Be careful with Downloads unless you have checked that folder yourself.

2. You can also use the old Disk Cleanup tool. Press Win + R, type:

cleanmgr

Choose C drive, then click “Clean up system files.” Again, avoid deleting Downloads or Previous Windows installation unless you know you do not need them.

3. After that, uninstall large apps you do not use:

Settings > Apps > Apps & features

For most people, Windows Storage, Disk Cleanup, and uninstalling large unused apps are enough.
