I want to download El Capitan, but KEEP the installer

I want to download El Capitan, but KEEP the installation program.

I have a partitioned hard drive, (I need to keep old versions of Mac OS because I do video editing).

How can I keep El Capitan Installer?   As many know, in the world of the downloaded software, installers can be removed or disappear. I like to keep a copy of things as much as possible.

Thank you.

As soon as the download is complete, it will jump to the top of the installation start screen. Press command-Q to stop the installation. Open the Applications folder and copy the El Capitan installer in any drive you want as a backup.
