Memory and Built-in Storage
The memory in the unit is used to store software applications,
configuration information, drivers and data. The unit has two kinds
of memory, flash and RAM. Flash memory is generally known as
Built-in Storage.
Built-in Storage memory is nonvolatile storage. The contents are
unaffected if the battery is removed or discharged. Therefore, you
should keep your data and software application programs in Built-in
Storage. The amount of Built-in Storage in your unit will vary
depending on your unit configuration. Windows Mobile™ 2003
software for Pocket PC’s uses approximately 26 MB of Built-in
Storage. The balance is available for your use. Third-party CF or
SD memory cards can be used to increase the amount of available
storage memory. They work the same as Built-in Storage, except
they are removable.
RAM is volatile. This means the contents will be lost if the battery
is disconnected or discharged. RAM memory is used to run
programs and is often used as the initial storage area for data. The
amount of RAM in your unit will vary depending on your unit
configuration. Approximately 18 MB is reserved for the operating
system. To save RAM memory contents into Built-in Storage, use
the pre-installed Sprite Backup program. See the next section
"Backup and Restore" for more details about backing up data to
memory. Any data in RAM that is not stored to Built-in Storage will
be lost if the battery is removed or discharged. We strongly
recommend regularly saving your data.
The following illustration shows the different kinds of memory as
they appear within File Explorer (Start / Programs / File
Explorer). The nonvolatile Built-in Storage is shown under the top
level My Device at the top of the list
. Tap on the desired folder to
