I just formatted my PC, when asked for a Username, I decided to do an experiment, and create a Username written with my native language (Armenian). After a while I got in some trouble, because of my Username written in my native characters I was unable to run anything from Desktop, User documents. So I decided to create a new account, with English letters, delete the old one with native letters and live on. After doing so, the PC works fine, though I see a very strange folder inside my C:/Users directory, here is a screenshot: I really wonder what that blank folder is, and what it is doing there. Thanks in advance.
