<section id="GUID-4A1719B9-BD5A-4D46-A196-E8447C144F91"><title>Pre-Symbian platform v9.0</title> <p>Application program files
must be located in directories with the form <filepath>\system\apps\&lt;program&gt;\</filepath>.
Initialisation and configuration files should be in the same directory, or
where the application is in ROM, in the equivalent directory on a writable
drive. </p> <p>Document files can be located in any directory <i>except</i> <filepath>\system\</filepath>,
and may be given any name: the system will not alter the capitalisation of
that name, and will not attempt to add or remove any extension. </p> <p>The
application architecture does not dictate the requirements for <i>all</i> files,
or even all file stores. For instance, an e-mail application is not document
based. An e-mail subsystem would store its messages in a directory structure
using special e-mail policies to implement inbox, outbox and folders. Normally,
this folder would be in a <filepath>\system\</filepath> directory. </p> </section>
