What is considered low flash memory?
The BlackBerry smartphone's Java® operating system has a complex and dynamic way of determining exactly how much available flash memory it should have before starting the Low Memory Manager application. To determine if it has low flash memory, the BlackBerry smartphone takes into account a number of factors, such as the BlackBerry smartphone hardware model, the operating system version, the number of installed applications, the frequency at which BlackBerry smartphone user data is added and removed, and so on. Generally speaking, the more the BlackBerry smartphone is used, the more memory the operating system sets aside for normal, efficient operation.
Note: When the BlackBerry smartphone has determined that is has low flash memory, it automatically starts the Low Memory Manager application, which reclaims memory.
The File Free field shows 0
When the File Free field shows 0, it most likely means that the BlackBerry smartphone is full of data. The BlackBerry smartphone determines that it has low flash memory and performs more extensive garbage collections in order to make room for any new data. However, even when the BlackBerry smartphone is full of data, it is designed to operate properly. The Low Memory Manager application starts recovering flash memory when data is added that requires additional flash memory.
How the Low Memory Manager application works
The Low Memory Manager application works to recover flash memory by removing old and unimportant data; when the Low Memory Manager application is running, it does not affect the regular operation of the BlackBerry smartphone, so you are not aware that it is running. The Low Memory Manager application makes requests to all applications on the BlackBerry smartphone to recover memory. However, third-party applications must be specifically designed to interact with the Low Memory Manager application.
The Low Memory Manager application makes requests of the applications on the BlackBerry smartphone in the following order:
1. The Low Memory Manager application first asks all applications to remove low priority data (for example, transitory data such as browser caches). If step 1 does not recover enough free flash memory for normal operation, the Low Memory Manager application asks the applications to remove medium priority data (for example, very old messages, cached map data, and out-of-date calendar entries).
2. If step 1 and 2 do not recover enough flash memory, the Low Memory Manager application prompts the Messages application to remove email messages starting with those that are the least frequently accessed.
How to maximize free space
It is a good idea to take active measures to maximize the BlackBerry smartphone's available flash memory, and thus, prolong the time before the operating system starts the Low Memory Manager application.
The following are suggestions on how to maximize available flash memory on the BlackBerry smartphone.
Use a media card
Media cards are especially useful for BlackBerry smartphone users who want to store media files like songs, pictures, videos, voice notes, and ring tones, or who want to store pictures they take with the built-in cameras. Built-in video cameras on BlackBerry smartphones require a media card to function.
To make sure the built-in camera is set up to save picture files on the media card, complete the following steps:
1. Install the media card in the BlackBerry smartphone. For more information, see KB12882.
2. Open the Camera application (for BlackBerry Device Software 6.0, tap All, then open the Camera application).
3. Display the menu and select Options.
4.
Set the Store Pictures field to On Media Card. You can also change the folder setting to the particular folder in which you want to save pictures.
Note: For BlackBerry Device Software 6.0, this option has been removed. However a different location can be specified when the file is renamed after image capture.
Remove unnecessary items
Removing features and applications that are underused increases the available flash memory on the BlackBerry smartphone.
*
Use the Setup Wizard application to remove languages that you do not use from the BlackBerry smartphone. Removing languages is highly recommended because it is one of the most significant ways to increase available flash memory.
To remove languages from the BlackBerry smartphone, complete the following steps.
For BlackBerry Device Software 5.0 and earlier
1. On the Home screen of the BlackBerry smartphone, open Setup Wizard.
2. Select Languages.

You can use this feature if your BlackBerry smartphone uses BlackBerry Device Software 4.0 and later and one of BlackBerry® Enterprise Server 3.5 or later for Microsoft® Exchange or BlackBerry Enterprise Server 2.2 or later for IBM® Lotus® Domino®.
Delete old items
The BlackBerry smartphone user can delete old and unused items and also adjust settings so that the BlackBerry smartphone deletes old items as part of its regular routine maintenance.
* Delete Multimedia Messaging Service (MMS) messages that are no longer needed. Because MMS messages can contain large media files and cannot be stored on a media card, MMS messages can use a lot of flash memory. If you do not want to delete the media files in an MMS message, open the MMS message and save the media files on the media card before you delete the MMS message.
* Change the Keep Messages setting on the BlackBerry smartphone to reduce the number of old messages using flash memory.
To change the Keep Messages setting, complete the following steps.
For BlackBerry Device Software 5.0 and earlier
