Yes is true... maybe.
I mean, whenever I've had to look into someone else storage to find something I always felt lost, more or less. The fact is what seem us intuitive and logical is often a cognitive bias.
So, I think the key, whatever the system you use, is to document your filling system. It is particulary true when you have to collab, share or transmit your infos, but even for a personnal use (do what I say, not what I do ). Maybe, however, this need is more important with tagging system (I feel so in any case).
