I am unable to index pdf files.  The following may be of some help

1. All pdf files have lower case extensions
2. xpdf is located in c:/xpdf
3. Some of the code in the conf.pl file include
        
        %EXT_FILTER = (
           "pdf" => "c:\xpdf\pdftotext FILENAME ",
           "doc" => "/usr/bin/antiword FILENAME"
);

        


  
        @EXT = ("htm","html","shtml","asp","pdf","doc","xls");




        
        @HTTP_CONTENT_TYPES = ('text/html', 'text/plain',
'application/msword', 'application/pdf');


4.  I can change pdf to text at command prompt.

5.  The error I receive is 
'-' is not recognized as an internal or external command,
operable program or batch file.

6.  html files are indexed
