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

#include <LFileAll.h>

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

....
.....private: // Data
	CLFileAll* iFileAll;
....

- 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 ELFileOperationsDeleteFile:
            {
		iFileAll->CallDelete();
            }
            break;
	case ELFileOperationsRenameFile:
            {
		iFileAll->CallRename();
            }
            break;
        case ELFileOperationsMoveFile:
            {
		iFileAll->CallMove();
            }
            break;
        case ELFileOperationsCopyFile:
            {
		iFileAll->CallCopy();
            }
            break;
	case ELFileOperationsFileExists:
	    {
		iFileAll->CallFileExists();
	    } 
	    break;
        default:
            break;
        }
    }

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