@ mak & trotter: i did unzip the only part with .zip only extension, the only file recognized by the PC as WinZip, the other files ends in .z01, .z02, etc (i.e. xxx.z01, xxx.z02, and on the type bar it is known only as Z01, Z02 files. Do I have to change the extension into .zip or add .zip after .z01?
