Can't you download the update from the Mac website? https://support.apple.com/downloads/macos

 

They also give advice on how to create a bootable installer for the OS: https://support.apple.com/en-gb/HT201372

 

Edit: I realize that it requires downloading the file again, but I don't think there is a way to get the information from the update that you initially downloaded unless it downloaded as a .dmg file (or whatever the filetype may be).
