"files catigurised, with lots of subfolders"

I usually sort my storage something like this:
---------------------------------
Audio
+ Albums
+ Singles
+ Random/Incomplete

Video (random files does not reach subfolders)
+ Music
+ + Live
+ + PVs
+ + Concerts
+ Movies
+ TV Shows

Images (random files does not reach subfolders)
+ Photobooks

Documents
-----------------------------

Saves more space than partitioning to keep all on one drive. My partitions look are on:
/
/home
[swap]
/media/hda5 (storage/torrents)


EDIT:
Most non-Audio is transferred too my external HDD.
