Use any of these methods to package applications for installation:

• You could package an application as a cabinet (CAB) file. Recommended

• For simple applications, the application itself may be the file to deliver.

• It could be a directory structure that contains the application, supporting 

files like ActiveX controls, DLLs, images, sound files, and data files.

Consider any of the following when choosing a location into which to store 
your application:

• In the basic CN30 Computer, there are two built-in storage options: the 

Object Store and the Flash File Store. The Object Store is a Disk on 
Chip (DOC) Flash that looks like a disk. The Flash File Store is an area 
of storage which is embedded in a section of the system’s FLASH mem-
ory. This storage area is not erased during a cold-boot. It may, however, 
be erased during the reflashing process. In addition to storing applica-
tions and data files, you do have the option to store a persistent registry 
to the Flash File Store region.

• If the optional Secure Digital (SD) storage card is in the system, then 

consider this card the primary location to place applications installation 
files. The “\Storage Card” folder represents the SD card.

• Use the small non-volatile Flash File Store region to hold CAB files that 

rebuild the system at cold-boot or install applications from a CAB file 
into the Flash File Store so they are “ready-to-run” when a cold-boot is 
performed. Since the FLASH in the system has a limited number of 
write cycles, do not use the Flash File Store for excessive writing pur-
poses; however, reading is okay.

CAB files (short form of “cabinet” files) are compressed folders as defined by 
Microsoft. A “cabinet” file is a single file, usually suffixed with .CAB, that 
stores compressed files in a file library. A compressed file can be spread over 
several cabinet files. During installation, the setup application decompresses 
the files stored in a cabinet and copies them to the user’s system. Intermec 
recommends using CAB files to install your applications. The CN30 Com-
