... and a smattering of other junk. Inbox - "stuff to process" that I don't have a habit or prompt to look at regularly
conf - backups of Win Task Scheduler tasks, Cobian Backup settings, theme, templates etc.
Dayplan - shortcuts to calendar etc. that hasn't really shaped up into a working system
"Personal" - mostly financial but some crossover into stuff that probably fits better in "Journals"
Career - historical resumes, references, job offer documentation etc.
Faith - notes and resources from church life and ministry
Journals (+ correspondence, gamemaster notes et al.)

... annoyingly, Windows also litters "My Documents" with crap like "Amazon MP3", Bluetooth Folder", etc.
... and a smattering of other junk.
It annoys me how Windows's scheme implies user/appdata carries as much significance as, say, user/mymusic, user/mypics and user/mydocs.
My own MyDocs looks a bit hodgepodgey too though:
"Personal" feels like a misnomer, but if I think about merging it with "Journals" then I start to bog down in a recursive contemplation of the significance of the "My Documents" designation. On the other hand I'm also not sanguine on unbundling it and treating the My Docs root as the dumping ground for an open-ended pool of journals etc.
