<concept id="GUID-5F749184-C804-41FC-BA81-038783BDC967" xml:lang="en"><title>Resources</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>In Symbian mobile application development, resource files are
used for defining user interface components and visible text. The
advantage of using resource files include:</p>
<ul>
<li><p>making source code shorter and simpler</p>
</li>
<li><p>saving memory, because text is loaded only when needed</p>
</li>
<li><p>making it easier to implement localization to different
language groups</p></li>
</ul>
<p>A key example of the use of resource files is found in the implementation
of <xref href="GUID-F3262DF6-39CA-4E96-AD0E-C1FFDE9B0A61.dita">AVKON components</xref>. AVKON UI components consist of data structures that are defined
in the <ph>resource
files</ph> , and then are called from the classes controlling the UI implementation.
When UI component implementation is split into these two approaches,
it means that resources can be recompiled, for example for new languages,
without having to recompile the application code.</p>
