<h5 id="C1_Util_DX_DirectWrite_FontFileStream_GetFileSize_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>Implementing GetFileSize() for asynchronously loaded font files may require downloading the complete file contents. Therefore, this method should be used only for operations that either require a complete font file to be loaded (for example, copying a font file) or that need to make decisions based on the value of the file size (for example, validation against a persisted file size).</p>
