What is an MPK File?

How to Open, Edit, & Convert MPK Files

A file with the MPK file extension is an ArcGIS Map Package file that contains map data (layouts, embedded objects, etc.) in one file that's easy to distribute.

The MPK file format may also be used for Project64 Memory Pack files or Public Browser Platform Configuration files.

Note: If what you have is a video file, it's more than likely an MKV file that you're misreading as an MPK file.

How To Open an MPK File

MPK files that are ArcGIS Map Package files can be opened with Esri's ArcGIS program.

ArcGIS Map Document files (.MXD) are embedded in MPK files and can be opened with the same software.

With ArcGIS open, you should be able to drag the MPK file directly into the program. Another way is to right-click or tap-and-hold on the MPK file to get to its context menu, and then choose Unpack. The map packages will unpack to the user's \Documents\ArcGIS\Packages\ folder.

Note: ArcGIS began using MPK files in version 10, so older versions of the software can not open MPK files.

Project64 Memory Pack files that are saved with the .MPK file extension can be opened with Project64.

As of this writing, I don't have information on any specific applications that will view MPK files that are Myriad Communications Public Browser Platform Configuration files. If you know any more details on MPK files, please send me a quick email so I can update this page.

Note: Keep in mind what I said above about MKV video files.

It's easy to misread the file extension as an .MPK file. Some other file types that look similar include MPL, MPLS, and MPN. Another is KMP, which is a Korg Trinity/Triton Keymap file that you can open with Awave Studio.

If you find that an application on your PC does try to open the MPK file but it's the wrong application or if you would rather have another installed program open MPK files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an MPK File

You should be able to convert an ArcGIS Map Package MPK file using the ArcGIS program I mentioned above. This can probably be done through a File > Save As... or File > Export menu option.

Note: You can't convert an MPK to MP4, AVI, or any other video format because MPKs are aren't videos - they just contain map data. However, MKV files are video files, and so they can be converted to other video file formats with a free video converter.
