That's because, not for you, but often, filling the desktop with thousands of files is often a sign of not understanding hierarchical file systems. Another sign is the Documents directory with tens of thousands of files, often numbered.
Maybe yet another sign is the manual for my very first PC (Spring Circle Super Turbo XT with _eight_ Mhz!). I kept the manuals because they are so cute: they explain file systems the unix way, including the /dev /bin/ /usr /tmp etc. division. It had nothing to do with the way MS-DOS worked, except, as Viro said earlier, that it showed where the dos file system was a copy from, without the manual writer showing any understanding what directories were for.
Way back, 27 years ago I took /bin to be the location for deleted files, and moved everything I didn't need there.
