I have all the stuff I work on on my desktop. When that gets full, I move everything into a folder "Old Desktop" which I place on the desktop. Of course this isn't the first time I did that. So this folder contains a chain of many such "Old Desktop" folders :')
It leads to interesting discussions sometimes such as "why do you have a 200GB roaming profile???". Organisationally though I can find stuff back really easily. While I traverse the chain of "Old Desktop"s I see other documents from the same timeframe which brings me back really easily.
In fact more organised people are often surprised how quickly I manage to dig up ancient stuff for them. They tend to lose track of things over time, probably when they move to a new PC or file hoster or whatever. I've really become the "Do you still have that inventory from 2007?" guy at work. I see no reason to change it at all.
