This code is to filter the files of desired extension from a folder

Header Reqired:

#include <f32file.h>

Library Needed:

LIBRARY  efsrv.lib

CMyClass.h

In class declaration add these lines

RArray<TEntry> iFileList;

CMyclass.cpp

_LIT(KFileExtension,"*.mp3");
_LIT(KDirPath,"c:\\Nokia\\Sounds\\Digital\\");
  
 
void CMyclass::ListDirectory( )
{
     CDir* dirs = 0;
     CDir* files = 0;
 
     User::LeaveIfError(iFsSession.GetDir(KDirPath,KEntryAttNormal,ESortByName,files, dirs));
      
     TFindFile findFiles( iFsSession );
     TInt err = findFiles.FindWildByDir( KFileExtension, KDirPath, files );
 
     CleanupStack::PushL( dirs );
     CleanupStack::PushL( files );
 
//get files in base path
 
    while (err == KErrNone)
           {
              for( TInt i=0; iCount(); i++ )
                    {
                    iFileList.Append( (*files)[i] );
                    }
            err = findFiles.FindWild( files );
         }
   CleanupStack::PopAndDestroy( 2 );
}

Now iFileList contains the files of desired extension. Here the list will contain only the mp3 files from c:\Nokia\Sounds\Digital directory
