4 - 10 MC9500-K Mobile Computer Integrator Guide
Persistent Storage
Windows Mobile 6 protects all data and applications from power-related loss. Because Windows Mobile 6 mounts 
the entire file system and registry in persistent storage (rather than using RAM), MC9500-K 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 320 MB (formatted) for 
128 MB/512 MB configurations with Mobile 6.1, 270 MB (formatted) on 128 MB/512 MB configurations with Mobile 
6.5 or 680 MB (formatted) on 256 MB/1 GB configurations with Mobile 6.5 and MC959B-K with Mobile 6.1.
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 60 MB (formatted) for 
128 MB/512 MB configurations with Mobile 6.1, 58 MB (formatted) on 128 MB/512 MB configurations with Mobile 
6.5 or 117 MB (formatted) on 256 MB/1 GB configurations with Mobile 6.5 and MC959B-K with Mobile 6.1.
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 MC9500-K. Go to the Support Central 
(http://support.symbol.com) to download the appropriate developer kit.
