The BB supplemental article seems to say, only an APP can make a new directory in the sandbox. You must, however, be able to locate your file called 'War and peace or how I got divorced after buying a playbook" in the downloaded books section.
It seems the user can define: File.documentsDirectory (appname)/shared/.... documents or whatever under the APP that the data was derived. For example you put all your videos in a video directory like: you-tube-vids/shared/video123 ....

Here is an overview of the BlackBerry� PlayBook™ application sandbox file system layout for the latest release 0.9.2
Applications will be run in the directory we call "sandbox". Name of this directory is irrelevant and cannot be relied on. An application should not attempt to access any files outside of this directory. Sandbox is the default "working directory".

The structure is
app
data
tmp
logs
shared

All except shared are app's private directories, only the app can read/write files there.
The "app" directory is the link to where application files are installed (what was packaged in the bar file), these files are read only. For Adobe� AIR�, application files will be in subdirectory "air" (i.e. app/air/your_file). The private data directory is "data". Application has full access to this directory (read/write). The $HOME env var is set to this directory. To initiate the sandbox app may copy files from "app" to "data" (for example user modifiable config files) on the first run. The "tmp" directory can be used to create temporary files, application should take care of cleaning these files, but system may remove them at any time app is not running - so it cannot be used to persist data, only "data" directory should be used for this. The "logs" is used for development, application stdin and stdout is redirected to logs/log file, as well as "core" files will be created there if app crashes.

The "shared" is link to common location where all apps share files. It has the following structure:
photos
bookmarks
misc
books
documents
voice
downloads
music
videos

These directories map to the File class as:
Alias Path
File.applicationDirectory (appname)/app/air
File.applicationStorageDirectory (appname)/data
File.desktopDirectory (appname)/
File.documentsDirectory (appname)/shared/documents
File.userDirectory (appname)/shared/documents

See the thread Does the PB allow users to set up folders?, especially my answer there. (Note: I wrote part of the article Missing_KW linked to at the top of this thread, so you can trust that my answer accurately reports how the simulator works, though there's always the chance the final release acts a bit differently.)

I haven't had a chance to read all the information but I was hoping for a folder layout similar to this:

Personal
- Documents
- Pictures
- Videos
Business
- Documents
- Pictures
- Videos
Home
- Owners Manuals


OR

Documents
Personal
Business
Pictures
Personal
Business
Videos
Personal
Business


Of course it depends on how RIM set it up but I would hate to have an Tank layout installation video for work right next to the movie Slap Shot because it makes sense alphabetically.

And this thread is perfect. I actually just asked this question on the main page under the unanswered questions post. Well that and of course the unanswered question we all want to know which is will forum posters learn how to use search instead of creating yet another Staples thread.
