At 8 years I recycled filesystem directories. I didn't know you can create new folders, so when I needed one I grabbed a random one from C:\Windows, moved it to my desktop and deleted its contents.
I wonder if Microsoft did focus group testing and found understandably computer illiterate people were concerned about "trashing" files meant they were somehow permanently using up HDD space
I was doing that at three or four and was reminded of it constantly for the next ten years or more. (I actually raised the subject on my mother's death bed.)
