>I want to create my exe files as soon as possible small size because some exe files goes to 4-5 mb somtimes.That's way I want to use external library such as fll or dll which contains my forms,reports,prgs.. all my anythings etc .

An FLL is used to write C code to access the VFP API, and do things you couldn't otherwise do in VFP, and FLLs would be totally unrelated to what you want to do. Compiling to a DLL won't gain you anything, because it's still VFP code and a DLL does not compile any smaller than an EXE (or it's negligible if it does).

Do you have the Debug Information checkbox unchecked? That can add some bloat to your EXE.
