One night I had 90gb free storage but 1 day later I only had 62gb.
I havent installed anything neither update my windows.
If anyone knows a fix tell me
Perhaps it was accumulated temp files and windows updates. Are you using OneDrive? Perhaps it’s cleared out a bunch of files you’ve not used in ages?
There’s just too many blanks here for people to be able to help you.
What kind of programs do you use? Video editing? I’m sure not.
Anyway, do what other people said. There are many “show me where the disk space is” kind of programs. I use Tree Size Free, it shows an explorer-similar view with a graphical interface, and sorts the folders by size in disk.
But even with this type of programs, you may not know how you went from 90 GB free, to 62 GB.
You need to tell us more of how you are using your computer, what did you do the day before, and what did you do after.
