This Windows folder on my computer hoarded 80 GB of junk — you might want to check yours

My laptop recently warned me that I had low storage even though I hadn’t installed anything new. I ignored it at first, thinking it was just another Windows glitch. A few days later, the system started slowing down, so I opened the Storage page in Settings to see what was taking up too much space and noticed one category that had grown unusually large. When I looked inside, the cause of my storage problem was obvious.
