minimizing the number of reads and writes to a file, removing unneeded debug logging, and minimizing file
flushing or closing files.

Persistent Storage

Windows Embedded Handheld 6.5.3 protects all data and applications from power-related loss. Because
Windows Embedded Handheld 6.5.3 mounts the entire file system and registry in persistent storage (rather
than using RAM), MC45 devices provide a reliable storage platform even in the absence of battery power.
Persistent storage provides application developers with a reliable storage system available through the
standard file system and registry APIs. Persistent storage is optimized for large reads and writes; therefore,
applications reading and writing data in large chunks tend to outperform those applications reading and writing
small blocks of data. Data in persistent storage is lost upon a clean boot.
Persistent storage contains all the directories under the root directory except for Application, Cache Disk, and
Storage Card (if a storage card is installed). Persistent storage is approximately 650 MB (formatted).

Application Folder

The Application folder is a super-persistent storage that is persistent even after a clean boot. Accessing data in
the Application folder is slower than accessing persistent storage. The Application folder is used for
deployment and device-unique data. For example, network profiles can be stored in the Application folder so
that connection to the network is available after a cold boot. The Application folder is approximately 96 MB
(formatted).

Enterprise Mobility Developer Kits

The Motorola Enterprise Mobility Developer Kit (EMDK) family of products allows you to write applications that
take advantage of the capture, move and manage capabilities of the MC45. Go to the Support Central
( http://supportcentral.motorola.com) to download the appropriate developer kit.
