There is still no short term baggage storage in CDG terminals, for security reasons. For storage durations above 6 hours, baggage storage can be provided by
Bagages du monde, with service desks in CDG 1, CDG 2A (landside), and CDG 2F (landside, arrivals level). I have used them twice already, for 2 to 7 days and found them useful. Baggage is registered at the service desks but is promptly moved to/from a secure storage area in the CDG cargo zone.
