I have a fairly simple system for my computer files that I download or clip from the web.
I’ve made folders for the different areas of my life or areas of interest a’la Tony Robbins’ OPA/RPM life planning methods. For example I made the following folders

financial
family/friends
career/work
health/fitness
spirituality/emotions
self study

As you can see these cover most areas of my life, yours might be different and you might have more or less areas. After making these folders I then could download info to them when I save a clip from the web or I could put documents pertaining to that area in the matching folder for later reading.

I also made the same folder names in Outlook so I could file my emails according to my life areas this makes review and searching so much easier.
