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.
