the format of the files on the internal NVFS partition is not too complicated. If you want you can just read and write to them directly. If you try to open them, you will get an error, but if insted of "read" or "readWrite" mode you pass ZERO, you will be allowed read/write access to the files in the PALM_DM folder.
