Imagine if the messier your bedroom got, the slower you moved through it, the molasses-like pace decreasing with each discarded magazine or sock. That's what happens to a computer desktop that's cluttered with files, as the machine is forced to constantly index, account for, and generally expend processing resources on those items in plain sight. A slow PC can often see a huge boost in speed, as soon as files are swept off the desktop, and into folders.
