# Obtain File Format Information

The File Content Extraction format detection module (`kwad`) detects a file's format.

This feature enables you to apply customized conversion settings based on a file's format.

To extract file format information

1. Set the input source using the `setInputSource` method.

2. Call the `getAutoDetectInfo()` method of the `Export` object.

   This method extracts the format, file class, version, and document attributes, and returns an object of the `AutoDetectInfo` class.

3. Use the methods of the `AutoDetectInfo` object to retrieve the format information.

The `HtmlTest` sample program demonstrates how to extract format information through the Java API. See HtmlTest.

## Example

    AutoDetectInfo adinfo = objHtmlExport.getAutoDetectInfo();
    if(adinfo != null)
    {
      outf_format = new File(docFormatOutFile);
      fos_format = new FileOutputStream(outf_format);
      DataOutputStream dos_format = new DataOutputStream(fos_format);
      dos_format.writeBytes("Auto-detection result: \n");
      dos_format.writeBytes("\nCharacter set:   " + adinfo.getCharacterSet());
      dos_format.writeBytes("\nDocument class:  " + adinfo.getDocumentClass());
      dos_format.writeBytes("\nDocument format: " + adinfo.getDocumentFormat());
      dos_format.writeBytes("\nFormat version:  " + adinfo.getVersion());
      dos_format.writeBytes("\nOther attributes:");
      if(adinfo.isAppleDoubleEncoded())
      {
        dos_format.writeBytes("\nApple double encoded.");
      }
      if(adinfo.isAppleSingleEncoded())
      {
        dos_format.writeBytes("\nApple single encoded.");
      }
      if(adinfo.isEncrypted())
      {
        dos_format.writeBytes("\nEncrypted.");
      }
      if(adinfo.isMacBinaryEncoded())
      {
        dos_format.writeBytes("\nMac binary encoded.");
      }
      if(adinfo.isWangGDLencoded())
      {
        dos_format.writeBytes("\nWang GDL encoded.");
      }
      dos_format.close();
      fos_format.close();
      adinfo = null;
