About compression

Compression is designed to reduce the size of your BlackBerry® device data while maintaining the integrity of that data. When compression is turned on, your device compresses all device data, including messages, contacts, calendar entries, tasks, and memos. You should keep compression turned on.

If both compression and encryption are turned on, your device compresses device data before encrypting it.

About file encryption

File encryption is designed to protect files that you store in the BlackBerry® device memory and on a media card that can be inserted in your device. You can encrypt the files in the device memory and on your media card using an encryption key that your device generates, your device password, or both.

If you encrypt the files using an encryption key that your device generates, you can only access the files on your media card when the media card is inserted in your device. If you encrypt the files using your device password, you can access the files on your media card in any device that you insert your media card into, as long as you know the password for the device.

Turn on encryption

To encrypt data in the device memory, you must have set a password for your BlackBerry® device.

Depending on the amount of memory available for storing files in the device memory, you might not be able to encrypt files in the device memory.
