88<H2>Description</H2>
89<p>
90Asynchronously creates a new file. The specified permissions and attributes are given to the file. <font color="#ff0000">However, the file must be granted at least the <CODE>NAND_PERM_OWNER_READ</CODE> permission. </font> If the <CODE>NAND_PERM_OWNER_READ</CODE> permission is not granted, the function will return <CODE>NAND_RESULT_INVALID</CODE>. <code>NAND_RESULT_BUSY</code> is returned and this function call is denied when the queue for accepting requests inside the library is full.
91</p>

93<p>
94This function updates the FAT of the Wii console NAND memory.
