Hi George,

You're mistaken. The fFlags member size is 2 bytes. Here's correct definition of SHFILEOPSTRUCT structure

lcFileOpStruct  = NumToLONG(_screen.hWnd) + ;
                NumToLONG(FO_COPY) + ;
                NumToLONG(lnStringBase) + ;
                NumToLONG(lnStringBase + LEN(lcSourceString)) + ;
                NumToWORD(lnFlag) + ;
                NumToLONG(0) + ;
                NumToLONG(0) + ;
                NumToLONG(lnProgressTitle )
