Excuse my ignorance (once again!) But could someone kindly explain where I store apps that appear on the homepage! I have recently installed a western digital passport external drive. And the passport logo is showing on the top right hand corner of my screen. I have tried dragging it to the applications folder in my finder but it is still there. It also shows a small black curved arrow when I try and move it! I ended up with quite a few of the same logo on my screen. So sent them all to my trash apart from original. Hope I haven't done anything wrong!!
