neko-office ftw.
The closest thing to a list I've ever made was an excel sheet that told me where my media files were - I had something like 8 IDE drives of various sizes stuffed full of junk.
Then I bought a 1.5 TB hard drive which consolidated all of that into one drive. Problem solved.
Lists are needed only if you have several storage locations and haven't used the 'one size fits all' solution. I love piles of things - clothes, bed, junk, garbage, me...
