Uh, no, France follows the European-wide bachelor's master's doctorate system when it comes to granting european credits. Which means that, yes, you can follow the normal cycle of 3 years (license/bachelor's), 5 years (masters), 7 years (doctorage), and these will basically count if you're looking to study abroad.
Some of my coworkers have 2 years of studies (IUT/BTS). Some have 4 (M1). Some of the PhDs in my company have 9 years, other 11, others are both working and researching at the same time. There's no mandatory 3 years.
