is the first place to look. Not knowing what you use, no one can tell you where to find this. In Firefox it's under Tools/Options/General. The default download folder is usually your user download folder but you can move it if you wish. You'll need to check your browser settings for this.
I always could download a photo I liked on facebook or where ever. it would save in Downloads. For some reason now it goes to "Movie Maker" then I have a hard time getting out. I am not smart enough nor do I want to make a movie. HELP!!!
