When you add a row with gtk_tree_store_append or cousins, the
GtkTreeIter is stored in the variable you pass to it as second
parameter. It's a return value.

GtkTreeIter iter;

gtk_tree_store_append   (store, &iter, NULL);

The GtkTreeIter of the newly created row is stored in the "iter"
variable.

void 
gtk_tree_store_append   (GtkTreeStore *tree_store,
                         GtkTreeIter *iter,
                         GtkTreeIter *parent);
                                      ^^^^^^

Pseudo code should look like:

gtk_tree_store_append   (store,
                         iter,
                         NULL); //root no parents

SET "/home" on iter

gtk_tree_store_append   (store,
                         iter2,
                         iter); // parent "/home"
SET "/someuser" on iter2

gtk_tree_store_append   (store,
                         iter3,
                         iter2); // parent "/someuser"

SET "/subdirs" on iter3
