When I tried to take a system image of my daily driver laptop, I didn’t have enough space on my backup drive. I didn’t remember doing anything extraordinary so I started looking for wasted space. I ran Windows’ tools without getting much back. So I started looking for tools in my “Software” folder. I found TreeSize Free and ran it. The answer stuck out like a sore thumb. It was in C:\Users\%username%\AppData\Local\Temp. In a future post, I’ll explain what had created all those files.
