Open a file for reading. 
<p>
Prepares the Filing System to read a data file from the storage. Files are referred to by their numbers, not file names. This makes the system generic, not necessarily needing a complex file system such as FAT. The way to assign numbers to files is implementation dependent. Returns 0 when ok, error code otherwise. <dl compact><dt><b>Parameters:</b></dt><dd>
  <table border="0" cellspacing="2" cellpadding="0">
    <tr><td></td><td valign=top><em>fileNumber</em>&nbsp;</td><td>number of file, starting from beginning of storage, to open.</td></tr>
  </table>
</dl>
What this function actually does, is: it starts reading the FAT records from start of the root directory, traversing through subdirectories as it encounters them. When the fileNumber'th valid record is encountered, it sets sectorAddress to point to its first data sector but doesn't load any sector. fileSize is loaded with the size in bytes indicated in the FAT record.<p>
Additionally, if it's called with 0 as the fileNumber and it happens to see an empty directory record, it registers a new file with name RECnnnnn.WAV starting from cluster fragment[0].start with file size from fragment[0].length
