I know this thread is very old, but I thought I'd post an update on it anyway. I recently came across a program called
Fences. Fences allow icons to be placed within specified areas of the desktop and lets then scroll, without scrolling the entire screen like
WinScroll. This is great, because I can now create a single fence the size of the desktop and place any number of icons in it and watch it scroll. This was what I was trying to achieve. Unfortunately, fences does not support details view or even list view, only large icons at the moment. I tried combining it with something like
Pitaschio, which can do list view, but the end result was not that good, with icons overlapping etc.
Fences also has a paid version,
Fences Pro, which allows sorting icons by date, type, filename etc. I have not tried it, so I am not sure how good it is. For someone not looking to use list view on the desktop, Fences is the best way to have unlimited icons on the desktop.
