Guillaume,

File() will return TRUE for both built-in/external tables/files

FileExists() will return TRUE only for external tables/files (RunTime, this is)

*--------------------------------------------------------------------------
Function	FileExists(FileName)
        declare Integer GetFileAttributes in win32api string @

	return (GetFileAttributes(@FileName) <> -1)
endfunc
*--------------------------------------------------------------------------
