There's also no harm in leaving it there and not worrying about it. Of course, if you are like me, you can't go on with your life without knowing what causes that folder to appear. The simplest way to find out might be to erase it, then leave your home folder open in a small window on your screen, so you can keep an eye on it, and see if you can notice when the folder appears. It will no doubt be the result of something you do in one of your applications, e.g., launching, importing or exporting, printing, etc. You can also do a Get Info on that folder and see when it was created. If you figure it out, please post and tell us.
