Following code snippets are different fucntions which can be perfomed on Fodler/Directory.

		TBool MkDir(const TDesC &aPath); //RFs
		
		//The directory must be empty and cannot be the root directory.

		//The directory may not be empty and can remove all sub files too

- Paste LFolderAll.h header file in your inc folder. - Paste LFolderAll.cppsource file in your src folder. - Include this LFolderAll.h your CYrAppUi.h file.

#include <LFolderAll.h>

- Declare an object in your CYrAppUi.h file.Like:

....
.....private: // Data
	CLFolderAll* iFolderAll;
....

- Finally call these fucntions from the HandleCommand() from CYrAppUi.Cpp file. Like:

void CYrAppUi::HandleCommandL( TInt aCommand )
    {
    switch( aCommand )
        {
        case EEikCmdExit:
        case EAknSoftkeyExit:
            Exit();
            break;
        case ELFolderOperaionsCreateFolder:
            {
		iFolderAll->CallCreate();
            }
            break;
        case ELFolderOperaionsDeleteFolder:
	{
		iFolderAll->CallDelete();
	}
	break;
        case ELFolderOperaionsDeleteFolderAndFiles:
	{
		iFolderAll->CallDeleteFolderAndFiles();
	}
	break;
        case ELFolderOperaionsDeleteFolderTree:
	{
		iFolderAll->CallDeleteFolderTree();
	}
	break;
        case ELFolderOperationsDeleteSpecificFiles:
        {
                iFolderAll->CallDeleteSpecificFiles(_L("*.xml"));
        }
        break;
 
        default:
            break;        
        }
    }

NOTE: You need to add efsrv.lib, bafl.lib in your .mmp file.
