Where are the settings stored?

Like most GNOME software, it uses the dconf database. The paths of the settings in this database are settable with the gsettings command or with the "dconf-editor" app.

The extension itself has almost no settings: since the folders are a native GNOME Shell feature, the keys already exist in the dconf database even if the extension isn't installed (you can use shell scripts to automate their creation if you have multiple machines or sessions).

Paths using the dconf editor:

/org/gnome/desktop/app-folders/folder-children contains a list of folder ids
/org/gnome/desktop/app-folders/folders/[some folder id]/name contains the name of the folder
/org/gnome/desktop/app-folders/folders/[some folder id]/apps contains a list of app launcher names (ending with .desktop)
if you don't want to add each individual app to folders, it's more efficient to use categories: /org/gnome/desktop/app-folders/folders/[some folder id]/categories contains a list of categories (see the standard concerning app launcher categories here and here)

With the gsettings command and a "Games" folder, it's like

gsettings get org.gnome.desktop.app-folders folder-children
gsettings get org.gnome.desktop.app-folders.folder:/org/gnome/desktop/app-folders/folders/Games/ name
gsettings get org.gnome.desktop.app-folders.folder:/org/gnome/desktop/app-folders/folders/Games/ apps
gsettings get org.gnome.desktop.app-folders.folder:/org/gnome/desktop/app-folders/folders/Games/ categories

gsettings set org.gnome.desktop.app-folders folder-children ['Whatever', 'Sundry', 'Games']
gsettings set org.gnome.desktop.app-folders.folder:/org/gnome/desktop/app-folders/folders/Games/ name 'Games'
#gsettings set org.gnome.desktop.app-folders.folder:/org/gnome/desktop/app-folders/folders/Games/ apps [] # useless here
gsettings set org.gnome.desktop.app-folders.folder:/org/gnome/desktop/app-folders/folders/Games/ categories ['Game']
