The Kajero (Esperanto for “notebook”) is the section of my Notkesto where I store general information; that is, where I store most of the Folioj.
The Kajero aims to be mostly in French, just like Tagnotoj.
There is a small portion of Folioj that are kept in the Kursujo folder, inside the relevant course folder. These Folioj tend to be in Spanish, just like the Kursujo.
The Kajero resides in the aptly named Kajero folder.
