I was on a search for the 'perfect' system all my life.

And I found it after 40 years : The No-System System... and it's the exactly opposite of op's suggestion :-)

All together in somewhat chaotic folders and subfolders... the clou is that I use "recoll" everytime i search something. It's an Index based search engine. Take a look...

I never missed something since I use just recoll and throw things just anywhere in the huge black box.

The main pro: it costs me no time to "sort" things into things.
