You are actually flying AF007 which arrived at terminal 2E, and you're departing on AF1532 which leaves from 2D. You can easily walk between those two in about 10 minutes maximum. When you check in you'll get an AF airport diagram with you bag tag attached. Ask for one if you don't. Don't forget to use "Aces No 1" because that will save you a few minutes.

Your bags will have no problem connecting, and if you're nervous ask the gate agent for the Athens flight to check.

Despite the horror stories, if you pay attention to signage and don't rush you'll have no problem. Don't take the bus, that will take more time and you'll walk just as far as if you walk E to D.

People are helpful if you ask, but just look at the monitors to see your departing gate because the access differs within the same Terminal depending on the gate range. That is where many people get confused.
