Format your media card or built-in media storage
Depending on your BlackBerry smartphone model, you might not be able to format your smartphone's built-in
media storage.
CAUTION: If you format your media card or built-in media storage, all of the data that's saved to your media card
or built-in media storage is deleted. Research In Motion recommends that you regularly create and save a backup
file on your computer, especially before you update any software. Maintaining a current backup file on your
computer might allow you to recover smartphone data if your smartphone is lost, stolen, or corrupted by an
unforeseen issue.

About compression
Compression is designed to reduce the size of your BlackBerry smartphone data while maintaining the integrity of
that data. When compression is turned on, your smartphone can compress your data, including messages,
contacts, calendar entries, tasks, and memos. You should keep compression turned on.
If both compression and encryption are turned on, your smartphone compresses smartphone data before
encrypting it.
About file encryption
File encryption is designed to protect files that you store on your BlackBerry smartphone and on a media card that
can be inserted in your smartphone. You can encrypt the files on your smartphone and on your media card using an
encryption key that your smartphone generates, your smartphone password, or both.
If you encrypt the files using an encryption key that your smartphone generates, you can only access the files on
your media card when the media card is inserted in your smartphone. If you encrypt the files using your smartphone
password, you can access the files on your media card in any smartphone that you insert your media card into, as
long as you know the password for the smartphone.
Turn on encryption
To encrypt data on your BlackBerry smartphone, you must set a password for your smartphone.
Depending on the amount of storage space available, you might not be able to encrypt files on your smartphone or
on your media card.
