I am a Mac user so I know that my computer is different. However, it took me a while to realize that my computer had a "default" which sent all my downloads to a (you guessed it) a "downloads" folder. LOL Boy did I feel - well you know? Now I am careful to "save as" and pick where my downloads go because in the "download" folder they have strange names that I cannot always identify. I am much more careful now and if I forget, I go through my download file and start opening them up until I find the one I want and then "save as" where I want it or can find it more easily.
I have to say...I really hate that my computer is smarter than I am. UGH
