<concept id="GUID-BB9760B4-4F3F-5326-81FB-B644C82F0E65" xml:lang="en"><title>File Server</title><shortdesc>Symbian platform manages the basic permanent storage of data through
file systems. Drives and file systems are common resources used by many programs,
and access to them is managed by the <i>File Server</i>. The File Server is
flexible, and can use many different file system formats and physical storage
media. Applications and services access files, directories, and drives through
the File Server client side API. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p id="GUID-320ADCFB-8449-541D-99A5-68F29A815559"> The different storage media
on a phone can use different types of file system to organise files. Symbian
platform provides a number of types of file system. You can implement a new
file system in a type of DLL called a file system plug-in. You can also implement
DLLs called a file server extensions to change the behaviour of a file system.
You can implement a DLL called a file server plug-in to extend the behaviour
of the File Server itself. </p>
<p>The File Server is started by the Base Starter component. The configuration
of the File Server, such as which file systems are loaded to which drives,
is done in the Base Starter configuration file. </p>
