Description
Flash memory is a file system that stores application and user data on the
BlackBerry® device. It cannot be physically removed from the BlackBerry
device. Sections of flash memory can store files that the user downloads or
saves manually to device memory.
An NV store (non-volatile store) persists in flash memory and can only be
overwritten by the BlackBerry device operating system. Third-party
application code cannot write to the NV store. The device erases flash
memory during a device wipe only.
Stores files that the user saves manually on the BlackBerry device. The
user might save files to an external memory file system (for example, a
removable media card) or to internal device memory that the BlackBerry
device treats and exposes like an external memory file system. The
BlackBerry device erases internal 'memory card' file systems during a
device wipe.
External memory file systems can be installed, accessed, and encrypted on
the BlackBerry device. The BlackBerry device does not erase external
memory file systems during a device wipe.
