These people don't know what they are talking about,I had the same question, "why does .chat_temp" keep popping up after it's deleted", so I investigated that shit. It has nothing to do with snapchat, is text messaging. You want actual proof? Delete the file, them have somebody text you while you have the done manager open, when they have sent you a text, view that text, then go back to the file manager and you will see that ".chat_temp is back I the file manager. This WILL help your inquiry. You're welcome
