where can I download ?

[szhiy.14]

I read from "UM1727 User manual" The STM32 Nucleo examples, applications and demonstration are provided in one single .zip file. The extraction of the .zip file generates one folder, STM32 Nucleo_FW_VX.Y.Z, which contains the following subfolders.

I want to know where can I download this kind of .zip file .
