you are very organized. my desktop looks like an icon dart board :-D
I just wanted to answer this on the way out the door for work. I can think back and can't every remember having a dartboard of a desktop. Even when I've had a generic colored screen ( non-image) I still corralled groups of icons together by type: browsers, audio, video, system, remote drives, paint, word processor, etc. I got jiggy quickly if I have to search for anything, and even my DESKTOP folder which holds other programs has subfolders accordinng to the samples above.
Not saying I'm any good with computing, I'm surely average user, and I'm not anal either, but when it comes to finding things, others could find stuff on my PC almost as quickly as I do :)
Have a great day!!!
