GeoUnpackA map package bundles a whole map. Several layers and their data. GeoUnpack lists all the layers inside and lets you preview and export them.
What is inside a map package
A map package is a 7-Zip archive holding the map document (.mxd for ArcMap .mpk, .mapx for ArcGIS Pro .mpkx) and a copy of the data for every layer in the map. The data usually sits in one or more file geodatabases, sometimes next to loose shapefiles, and is often duplicated for different ArcGIS versions. GeoUnpack scans all of it, keeps the newest copy, and shows one row per layer or table, labelled with the geodatabase it comes from when there are several.
What you can and cannot see
- You can see every vector layer, its feature count and coordinate system, and preview it on a map.
- You can see standalone and related tables, including attachment tables (names ending in
__ATTACH). - You cannot see the map layout, layer order, symbology or labels; those are in the map document, which only ArcGIS opens.
- Basemaps are not in the package at all. They are online services the map pointed to.
How to use it
- Drop the .mpk or .mpkx file into the box.
- Browse the layer list; click Preview to see a layer.
- Select layers and export them to the format you need.

FAQ
What is an .mpk file?
An ArcGIS map package. It contains the map document (.mxd or .mapx) plus copies of the data for every layer, usually in file geodatabases.
Can I open the map layout?
No. GeoUnpack extracts the data layers. Map layouts, symbols and labels require ArcGIS.
