Transfer your files to another storage device. Reinstalling Windows on a new drive can erase existing data. Without additional drives, collect your available 4-8GB USB drives from school.
It seems your system is running well as expected. The hibernation file should be in the designated location, and the pagefile follows suit. This setup is relatively new for Windows 10, but your folder size is only 19GB. Given that it's over 25GB, the hibernation file might be occupying space. If you don't need hibernation enabled, consider disabling it.
Even if it's not hibernation, reinstalling the system isn't a fix—once you restore all files, programs, games, etc., and use Win10 normally for a few days, the same amount of free space will return. Reinstalling Windows isn't a magic solution; it's merely a temporary workaround until the real issues are addressed.
