Device storage space
The BlackBerry device storage space consists of various sections that store BlackBerry device user data and sensitive
information such as encryption keys. Third-party applications on a device cannot write to or access the sections that store
sensitive information.
The following sections are a part of the device storage space.
Section Description
application storage The application storage is an internal file system on a device that stores
application data and user data. Application storage is the only place on a device
from which applications can be run. Sections of application storage can store
files that a user downloads or saves to device memory. You cannot remove the
application storage from the device.
The application storage is encrypted when content protection is turned on.
built-in media storage The built-in media storage stores files that a user saves on a device. The device
uses and exposes the built-in media storage the same way that the device uses
and exposes a media card.
When you permanently delete or a user permanently deletes all device data, the
device deletes all files from the built-in media storage, except for the file system
partition called System, which includes sample pictures and sample ring tones.
The built-in media storage is encrypted when content protection is turned on.
NV store The NV store persists in application storage, and only the operating system of
the device can write to it. Third-party application code cannot write to the NV
store.
media card The media card is a microSD card that a device user inserts in the device to
extend the amount of storage on the device. A user can save, access, and
encrypt files on the media card using the device.
When you permanently delete or a user permanently deletes device data, the
device deletes the files from the media card only if the device is running
BlackBerry Device Software 5.0 or later and if you configure the Media Card
Format on Device Wipe IT policy rule.
