Where is de save location located in Dreamfall Chapters?

I'm running Windows 8.1 My save location is

C:\Users\<Your User Name>\AppData\Roaming\RedThreadGames\DreamfallChapters\

The %appdata% folder is the one you have to look out for.

RTG wants to implement a new save system for Book 2 though, so watch out. The only data you will probably need to save for multiple playthroughs is the storyflags.data one. It is overwritten with your choices every time you finish the episode.
