Question: I am a citizen of India (third-country national?) and I currently reside in the United States. I will be joining a job in France on a "Long stay French visa". I was looking around the web to see if I could find correct information about whether or not I would be allowed to travel freely within the Schengen states on a long stay visa.

I came across [this answer](https://travel.stackexchange.com/a/11119/2236) which says that "Third-country nationals who are long-term residents in a Schengen state may also acquire the right to move to and settle in another Schengen state without losing their legal status and social benefits."

So assuming that I am a "third country" national, how do I **acquire the right** to travel for tourism?

I am yet to apply for a long stay visa but I was just considering my options and possibilities right now.

Answer: 
If you are a resident of one of the Schengen countries you can automatically travel in the other Schengen countries. This is not something you need to "acquire". 

In theory the 90/180 rule applies, but in practice there are no border checks between Schengen countries, and your movements are not tracked, so you are basically free to travel where you want, when you want.
Having a Schengen visa only gives the right to travel , not to reside in another Schengen country. Even EU citizens have to request a residence visa for any country other than their own after 3 months , and this will only be given if the person can prove being able to support themselves through having a job or pension . And the person will also have to register their national health card with the local health authority.
