Erasing file systems on BlackBerry devices 

 

Types of file storage systems on BlackBerry devices 

Type of memory 

Description 

flash memory (internal to 
device) 

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. 

memory card file system 
(external or internal to device) 

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.  

User data that the BlackBerry device stores 

The BlackBerry device stores user data items, including the following:
