As it turns out, there are lots and lots and lots of websites devoted to helping people manage their filing systems. (Apparently there is quite a need here.)
Rather than summarizing them all, I’m going to list out a few websites for your perusing pleasure:
Organized Artistry (“transforming mess into masterpiece”)
The Clutter Diet Blog: http://www.clutterdietblog.com/2009/04/national-organize-your-files-week-yippee.html
As it turns out, the third week of April is National Organize Your Files Week (who knew?), so while you’re cleaning out your files this weekend, be sure to put a note in your calendar for when you’ll tackle them again next year.
