One final point to remember is that you may carry gifts for French professionals you are going to meet, but it is not mandatory. If you don't know what to get, refrain from bringing anything. Just like business, there are specific types of gifts that are exchanged professionally. Books and music may make good gifts, but again, this depends on the kind of professionals you are going to be interacting with.
Respect the French business etiquette and you will be able to develop healthy and long-lasting business relationships with them. You will be greatly appreciated and respected for taking so much care in functioning according to their standards and protocol.
