How many genres can I have?

Probably a stupid question… but is there a limit to how many genre folders I can have?

Right now my folder structure looks something like this:

_wd.tv

movies

—> Drama

—> Comedy

—> Thriller

—> Crime

tv

—> Animation

—> Sci-fi

—> Drama

Under the movies folder and the tv folder is there a limit to the number of genre folders I can have?

There are no stupid questions. 

Only stupid people.

What I was told is the max # is 9 but there are ways around this.  Maybe someone here can add more information.

Your limited to main folders, not the genres folders the way you have it shown…
