MilX File Association: Open .milxlyz Files Directly

MilX (*.milxlyz) is the default file format used in map.army .

Start by double click

Once map.army is installed as a Progressive Web App (see ‘Install’), the desktop platforms — Windows, Mac, Linux, and Chrome OS — register MilX files with the operating system. A double-click on any .milxlyz or .milxly file in your file manager launches map.army directly and loads the layer onto the map — no need to open the browser first, navigate to the site, and import the file manually.

On mobile (Android, iOS / iPadOS) the operating system does not expose a file-handler API to PWAs — open saved overlays through the in-app Import Layer dialog instead.

Windows

After installing the progressive web application, the operating system recognizes .milxlyz and .milxly files. Double-clicking a file in Explorer launches the app and loads the layer onto the map.

Mac

After installing the progressive web application, the operating system recognizes .milxlyz and .milxly files. Double-clicking a file in Finder launches the app and loads the layer onto the map.

Android

Android PWAs do not register a .milxlyz file association in the system’s Open with registry. To open a saved overlay on Android, launch map.army from the home-screen icon and use the in-app Import Layer dialog instead — see Import MilX Layer.

Chrome OS

After installing the progressive web application on Chrome OS, the Files app recognizes .milxlyz and .milxly files. Double-clicking a saved overlay in the Files app launches map.army and loads the layer onto the map.

iOS and iPadOS

iOS and iPadOS PWAs installed via Add to Home Screen do not register a .milxlyz file association — Apple does not expose the file-handler API to web apps. To open a saved overlay on iOS, launch map.army from the home-screen icon and use the in-app Import Layer dialog instead — see Import MilX Layer.

Linux

On supported 64-bit distributions (Ubuntu 18.04+, Debian 10+, openSUSE 15.2+, Fedora 32+), the PWA install registers a MIME-type association for .milxlyz and .milxly and an Open With entry. Double-clicking a saved overlay in the file manager (Files / Nautilus, Dolphin, Thunar, …) launches the app and loads the layer onto the map.

File format

.milxlyz is the zip-compressed variant and .milxly is the uncompressed XML variant of the same MilX layer format. Both are handled identically by map.army — opened automatically when double-clicked on a desktop platform with the file association registered, or imported manually via the in-app dialog on mobile or in any browser session without the PWA installed. See ‘Import MilX Layer’ for the manual import flow.
