Sometimes it seems like modern computing is a constant battle to maintain enough free disk space for the data you need to stay productive.
Your adversaries are apps that chew up disk space when you install them and then continue gobbling up disk space with the data files they create. And then there's Windows itself, which uses disk space for its system files, for hibernation and paging files, and for System Restore points.
To find out exactly where your storage space has gone, open the Windows 10 Settings app, click System, and then click Storage. (You can skip all that clicking by typing storage in the search box and then clicking the top item on the results list.)
The overall view displays the capacity and used space for all available fixed drives. Click the entry for your system drive to see a bar chart that breaks down how it's being used, with a color-coded list of categories beneath it.
Keep drilling and you'll find some extremely useful tools:
