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> <section id="GUID-C8E8AB80-4EE5-5593-8981-4A91A0111419"><title>Symbian OS v9.0 and beyond</title> <p>The following table gives the location for different file types. </p> <table id="GUID-9952EBEF-FCBC-585F-A9AD-D1CD2F8088BA"><tgroup cols="3"><colspec colname="col0"/><colspec colname="col1"/><colspec colname="col2"/><thead><row><entry>Location</entry> <entry>Example file types</entry> <entry>Description</entry> </row> </thead> <tbody><row><entry><ul><li id="GUID-D669EB04-023C-5224-999D-9EE55E8EA7ED"><p>On the emulator (default): </p> <ul><li id="GUID-BEE962D9-B7DD-5B2B-91B3-125B16E414DC"><p> <filepath>epoc32\release\winscw\udeb\</filepath>  </p> </li> <li id="GUID-52700062-ED55-525D-BC55-A10678FC97E6"><p> <filepath>epoc32\release\winscw\urel\</filepath>  </p> </li> </ul> <p>On the emulator, e.g. for text notifiers: </p> <ul><li id="GUID-851A7FE9-54FE-5FEB-9F38-4B4F32EEDD53"><p> <filepath>\sys\bin\tnotifiers</filepath>  </p> </li> </ul> </li> <li id="GUID-726EA784-F425-5F5D-8837-33AA9244594E"><p>On the device: </p> <p> <filepath>\sys\bin\</filepath>  </p> </li> </ul> </entry> <entry><p> <filepath>.exe</filepath>, <filepath>.app</filepath>, </p> <p> <filepath>.dll</filepath>, <filepath>.ani</filepath>, </p> <p> <filepath>.ctl</filepath>, <filepath>.fep</filepath>, </p> <p> <filepath>.mdl</filepath>, <filepath>.csy</filepath>, </p> <p> <filepath>.ldd</filepath>, <filepath>.pdd</filepath>, </p> <p> <filepath>.prt</filepath>, </p> <p> <filepath>.ECOMIIC</filepath>, <filepath>.PLUGIN</filepath>  </p> </entry> <entry><ul><li id="GUID-2C766E8B-EB9E-5BA5-9E86-B69D1412E3AD"><p>Location of all binaries </p> </li> <li id="GUID-8443D832-175E-52DD-A190-2E4F0F86C02E"><p>The OS will refuse to load any binary not in <filepath>\sys\bin\</filepath>  </p> </li> <li id="GUID-6EF741B8-BA5E-592B-88AD-D74C18556797"><p>Code without <codeph>AllFiles</codeph> (or <codeph>TCB</codeph>) capability will never be able to read (or write) anything under <filepath>\sys\</filepath>  </p> </li> <li id="GUID-139E6964-311A-5B28-93A2-DABE9F176D1E"><p>Note that for the emulator when <codeph>PlatSecEnforceSysBin</codeph> is enabled (in the <filepath>epoc.ini</filepath> file) executables found under <filepath>\system</filepath> will not be able to be loaded </p> </li> </ul> </entry> </row> <row><entry><p> <filepath>\private\&lt;process SID&gt;\</filepath>  </p> </entry> <entry><p> <filepath>.doc</filepath>, <filepath>.txt</filepath>, </p> <p> <filepath>.xml</filepath>, <filepath>.dat</filepath>, </p> <p> <filepath>.ini</filepath>, <filepath>.mbm</filepath>, </p> <p> <filepath>.rsc</filepath>  </p> </entry> <entry><ul><li id="GUID-D3532BB0-FA8A-543F-90D2-FAF3A60D59FB"><p>Location of all private data files (e.g. if the file is to be accessed only by the application itself) </p> </li> <li id="GUID-9EC27287-26DC-5A60-AAB8-66CB9B542A3B"><p>The directory name under <filepath>\private</filepath> is determined by the SecureId (SID) of the process.
