How to root Samsung Galaxy A3 in order to recover removed data

[Kartm]

Hi!
I have recently removed some photos on my phone by accident.
I know that I can recover them if they are not overwritten, but my Samsung needs to be rooted.
I don't want to brick my phone and minimise the risk of overwritting the data.
My model is Samsung Galaxy A3 (SM-A300FU) with Android 6.0.1.

Is there already a well-explained way to root my phone? I need the simplest possible, step by step.

Yeah, but this one is for Lolipop, not Marshmallow.
