ListMetadataQuery query = new ListMetadataQuery();

 query.type = "ApexClass";

 double asOfVersion = 23.0;

 // Assume that the SOAP binding has already been established.

 FileProperties[] lmr = metadataService.listMetadata( new ListMetadataQuery[] { query }, asOfVersion); 

if (lmr != null) 
{
  foreach(FileProperties n in lmr) 
 {
  string filename = n.fileName; 
 }
}


 I m using this code to get list of Apex classes. 

I want list of folders for //***query.type = "EmailTemplate";***// component type. 

Is it possible using listMetadata() method or any other way to achieve this? 

please reply asap. 

thanks in advance.
