Most of them are critical, which is why Windows usually never lets you modify them. But the problem is, some of these system folders can easily take up gigabytes of storage space unnecessarily. And since they’re tucked away deep inside system directories, you never really notice them. While monitoring my PC’s storage with WizTree last week, I came across one such folder: Installer. It looked like any other system folder, but it caught my attention because it was taking close to 60 GB of storage. Naturally, I had to know what it was all about, and I’m glad I did because it helped me free up some much-needed storage.
