61<h2>Description</h2>
62    <div class="section">
63<p>Creates an expanded save data memory region.</p><p>Creates an expanded save data region corresponding to the ID. Use the expanded save data number specified in the RSF file as an argument indicating the expanded save data ID.</p><p>Before calling this function, you must call <a href="../../nn/fs/MountExtSaveData.html"><CODE>MountExtSaveData</CODE></a> and check if a memory region with this same ID has already been created. To only format the region, call <a href="../../nn/fs/DeleteExtSaveData.html"><CODE>DeleteExtSaveData</CODE></a> to delete, and then call this function.</p><p>For the icon data, specify the <CODE>icn</CODE> file output by the <CODE>ctr_makebanner32</CODE> tool.</p><p>Unless you re-create extended save data, writes cannot exceed the specified number of directories, number of files, or data size. Be very careful during extended use.</p><p>You cannot change the size of files created in expanded save data memory. Consequently, you cannot create files using functions such as <a href="../../nn/fs/FileStream/TryInitialize.html"><CODE>FileStream::TryInitialize</CODE></a>. When creating files, use <a href="../../nn/fs/TryCreateFile.html"><CODE>TryCreateFile</CODE></a>, for which you can specify the file size.</p><!-- write here --></div>
