I'm currently going through my fileserver and deleting a lot of files, including most of my University work from half a decade ago. I also no longer keep copies of media (music, movies) that I can get from somewhere else if I want it. I find it quite liberating to have fewer files. Filesystem clutter, like physical clutter, I find, leads to mental clutter, which I want to do away with. I suspect many of you have experienced something similar.
