 Khi bạn thêm hoặc di chuyển các điểm định vị, máy chủ của chúng tôi sẽ tính toán đoạn đường tốt nhất trên mạng lưới giao thông.
 Chúng tôi cũng sử dụng các API từ <a href="https://mapbox.com" target="_blank">Mapbox</a> để hiển thị đa dạng các bản đồ, lưu trữ các dữ liệu độ cao cũng như giúp bạn có thể tìm kiếm các địa điểm khác nhau.

-Unlike the file actions, the edit actions can potentially modify the content of the currently selected files.
-Moreover, when the tree layout of the files list is enabled (see [Files and statistics](../files-and-stats)), they can also be applied to [tracks, segments, and points of interest](../gpx).
+Không giống như các thao tác trên tệp, các thao tác chỉnh sửa có thể thay đổi nội dung của các tệp hiện đang được chọn.
+Hơn nữa, khi bố cục dạng cây của danh sách tệp được bật (xem [Tệp và thống kê](../files-and-stats)), chúng cũng có thể được áp dụng cho [đường đi, đoạn đường và điểm quan tâm](../gpx).
 Therefore, we will refer to the elements that can be modified by these actions as _file items_.
 Note that except for the undo and redo actions, the edit actions are also accessible through the context menu (right-click) of the file items.
