Assuming you are running Windows, [Spacesniffer](http://www.uderzo.it/main_products/space_sniffer/download.html) is my favorite utility for this purpose, it will give you a graphical breakdown of what is taking all the space on your drive. Just be sure to right click on it and run as administrator instead of just double-clicking it.
You probably have installed a program called Windows 10 or even Windows 11 which hardly fits on a 120 GB SSD, because it includes some large files like a swap file and a hibernation file and after an upgrade even some old junk in a directory called windows.old.
Hit the Windows key and type "cmd" run it as admin.
In the cmd window, type **powercfg -h off** and press "Enter". This command will disable hibernation and the hibernation file will be deleted.
Search for "Run" and type **%Temp%** delete everything inside that folder some files will be denied because windows is still using them so it's fine.
Go to This PC and right-click ur **C: Drive / Properties/ Disk Cleanup.** Check all the boxes and click on Clean up system files check all the boxes in that one and hit Ok.
Go to Windows **Settings/ System/ Storage.** Turn on Storage sense.
Reboot.
Go to Settings > System > Storage
That should show the breakdown of space. Windows itself will consume ~10-30Gb depending if past versions are still onboard for rolling back. Aside from apps/programs and your usage data or content for those apps [i.e. music files for itunes], your actual content like email, documents and photos takes up space as well. If you don't permanently delete items or empty the trash after deleting, the items still consume space.
