Before you delete the data from your BlackBerry® smartphone, consider backing up your data so that you have a copy on your computer. If you have turned on encryption, the process for deleting all smartphone data can take up to an hour to complete.

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.

1. Connect your smartphone to your computer.
2. In the BlackBerry® Desktop Software, click Device > Delete data.
   • To delete all your smartphone data, click All data.
   • To delete specific data, click Selected data. Select the check box beside one or more databases.
3. If necessary, do any of the following:
   • If your smartphone includes built-in media storage, select the Delete files in your built-in media storage check box.
   • To create a backup file for your smartphone data, select the Back up data before deleting check box. To encrypt the backup file, select the Encrypt backup file check box. Type a password.
4. Click Delete.
