[I posted these questions a while ago but got no response]
I'm writing an application that will target 4.2.1 and up. After reading all I can find (api docs, forum, kb, guides, web search), I still have lots of questions about the BlackBerry file system:

i'm not quite sure on your open questions, but i'll try to answer them best i can:
1. Haven't had any different namings on devices till today.
2. You don't have any problems on SDCard and you are allowed to save files anywhere there. Not quite sure
about store, but you should be able to save files on viewable file system and own created folders. There will be
some unreachable folders which the devices need for internal processing (f.e. installed applications etc.).
3. You can open files as readonly etc. but elsethere there aren't any security layers installed. If you have data
regarding security issues, you should save that f.e. using class RuntimeStore!
4. I don't know, but that is a fact. But therefor you can detect the mass storage activation/deactivation
5. See point no.3
6. See restrictions as specified in JSR 75.

Thanks for the info, Jochen. I've been experimenting with the simulator, and have observed the following.

I also have no idea if the behavior of the simulator differs significantly from real devices regarding the file systems store and SDCard.
The Simulator is faster when it comes to accessing data from the sd-card and store. That's about it. I've yet to see a build that works on the simulator and fails on the device. We also regularly exchange binary files between the microsd card of the device and the Simulator's "sdcard" directory. Fully compatible.
