Remove side menu(right side) from finder

When I open any Finder window it appears with options in the right side. I can hide it by dragging it to end. But if I open a new window of the finder it appears again. So, please help me to hide that options menu in Finder.

OS: Mojave 10.14.5

Look at the screenshot I posted, You'll see what you need to click in order to disable the preview in your Finder. My OS is in French and I don't know the name of the option in English, that's why I sent this screenshot.

You can click Finder > View > Hide Preview or just press ⇧⌘P when in column view. Changing the setting acts on all opened Finder windows and all subsequent Finder windows until one clicks Finder > View > Show Preview or presses ⇧⌘P again when in column view.
