That's what I call it when I sort through my files, put them in order and make sure that I've got them backed up to the right locations. It can take more time than most people are willing to give to housekeeping of any type, but I find it useful and relaxing. The OCD in me is soothed.
It is also a way to remind me of what I own and what I want to use next. If you are constantly digging through your stash, you have very little that you forget you own.
