+= File Ownership =
+In the minimal case, a nautilus file is owned by:
+- Window slot -> viewed_file
+- Window slot -> history list using bookmarks
+- Path bar -> button -> file
+- Path bar -> button -> nautilus_drag_slot_proxy
+
+When a file is a bookmark, nautilus application keeps a list with them, so it
+also owns those files.
+
+Window slot is the creator of the file if the file was already not present due
+to be a bookmark.
+
+The window has a queue with information of the closed tabs, owning references
+to previous files.
+
+= Directory Ownership =
+Every file has a directory associated, that is usually the parent. However, when
+the file is a root and has no parent, the file is called self_owned, and the directory
+and the file are the same location, but different objects.
+
+It's better to always deal with files instead of directories, and let the file handle
+the ownership of its associated directory.
+
+= View Ownership =
+It's owned by:
+- Window slot as a strong reference, since the view sinks the floating reference.
+So to freed it the window slot needs to destroy it with gtk_widget_destroy ()
+since it's the container, but also needs to unref it.
