In order to do that, you can either use avedesk (not really needed) or you can alter it in properties. Right click anywhere on your desktop, and select properties.
Select the Appearance tab and then go to the Advanced button in the bottom right corner. Then, in the "Item:" box, select "icon" instead of "Desktop" . T
here, change the size of your icons to anything that pleases you. There. Now, to space them. Select icon spacing (vertical) in the same box as before. Change that to any # you want, experimenting to get the right mixture.
Also, if you have several rows of icons on your desktop, (a couple rows), go to icon spacing (horizontal), once again in the same box. Change that to almost the same as the vertical icon spacing setting.
There. Now all you need to do is make them look cool!!!!
Hope I could help some and that you could understand me. If you didn't, then either pm me or just quick respond to this.
