System memory / application memory FS question

Does anyone know what file system is used in the system and or application storage?

 

I believe that Fat32 is used for media memory and SD cards (correct?) but I'm having trouble finding good information about how system memory (///store) and or application memory (///system) is managed by the device.

 

My Google-foo has failed me.

 

Also, In reading other peoples post as well as blackberry support docs I've seen a few different names used for the different areas of storage, I believe the above mapping is correct i.e.. if the device does not have separate built-in media storage then everything would be under ///store  while if the device does then the applications are stored in ///system which is protected.  In either case the SD card would be identified as ///SDCard....is this correct?

 

Thanks!

Sean

Re: System memory / application memory FS question

The file system is proprietary. No one besides RIM knows what it is.

Re: System memory / application memory FS question

//store is the internal SD Card, which you can browse using the File Application on BlackBery and as an external disk with the BlackBerry USB connected.   Not all devices have this. 

 

I've never heard of //system..

You've never heard of //system? If you have the native Files application on your BlackBerry, open it. Go to File Folders, then press the menu button and choose "Show Hidden". You'll see //system.

It has stuff like the sample pictres/videos, thumbnails, etc. Not really fully utilized.
