Can not create class from enterprise WSDL file in Salesforce

Hi all,

I have an enterprise WSDL file from another salesforce org, when I try to create a class to use this WSDL for SOAP API methods , it gives me limit exceeded error.

How can I reduce the WSDL size (lesser than 1 mb, currently it is 1.6 mb), should I just delete useless chunk of code from the xml file manually?

Any suggestions are appreciated.Thanks
