Best way for save project


I would like to save my project and add something like a version number to it. I use an example from nordic SDK. So in my case I use solution from ...\examples\ble_peripheral\ble_app_uart.

If I press "save all" in SES, only main.c is saved.

But I modify also files such as ble_nus.c, which is saved in folder ...\components\ble\ble_services\ble_nus

Is it possible, to create a folder with all "used and customized files" (.c and .h) in it?
