Hi,

I have a question about the root names for BlackBerry.

For example my Bold 9000, has 3 roots:

• System
• Store
• SDCard (if SD card is inserted) 

Does any one know, what is the purpose of 'system' root ? Are there any restrictions (read/write operations for any file operation ? ).

Thanks.

I can no longer access the system folder even for read access - I get a 'null' exception.  The system folder contains things like the default ringtones that your phone can use, but since you can't access the folder you can't leverage them.  Hope this helps.

Thanks,

I have tried at least in OS 4.6.0 I was able to create/rename/delete folders or files, except the files with *.rem extension for some reason, can't even read them.

 But I guess not all devices have system folder, so I probably shouldn't even touch it.

.rem files are the DRMed files. You can probably try reading them somehow with the ExtendedFileConnection class (I've never tried this myself).

I was able to access the system folder in 4.7 - I could even play .rem ringtone files, but even opening FileConnection on the root is throwing an exception in 5.0.  I think the best thing to do is to stay away from it.

Is it throwing a ControlledAccessException by any chance? If so, it's probably because your application is not signed by the proper signer whose ID is encoded in the .rem file. I suspect that in v5.0.0 that signer would probably be the RIMAPPS2 (aka "3") so that only RIM's own application can access these built-in media files.

Thank you for all your responses. I guess I shouldn't mess with System then
