I have a cloud folder where I store pretty much all data I care about, both for work and personal life (with exceptions like photos and videos, for space reasons). It used to be a huge mess and I often had a hard time finding a specific thing. I switched to J.D a few years ago - or rather to a modification of it, it's not strict: I do have a few "out of category" folders that were difficult to neatly categorize, for example - but the principles are there. And now I find it much easier to locate stuff.

In my case, though, looking for specific documents from several years ago is very common. Maybe if you don't have that need and can find things just fine with your current setup, J.D would do nothing for you.
