A file with the MPK extension is an ArcGIS Map Package file that contains map data (layouts, embedded objects, etc.) in one file that is easy to distribute.
The MPK file format can also be used for Project64 memory pack files or public browser platform configuration files.
If what you have is a video file, it is more than likely an MKV file which you are 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 (.MXD) files are embedded in MPK files and can be opened with the same software.
With ArcGIS open, you’ll 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 the context menu, and then choose Unpack . The map packages will be unpacked into the user’s N DocumentsArcGISPackages/em> folder.
ArcGIS began using MPK files in version 10, so earlier versions of the software can’t open MPK files.
Project64 Memory Pack files that are saved with the .MPK file extension can be opened with Project64.
If you find that an application on your PC tries to open the MPK file but it’s the wrong application, or if you prefer another installed program to open MPK files, change the default program for your specific file extension to make 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 mentioned above. This can probably be done via File > Save As…. or File > Export menu option .
You cannot convert an MPK to MP4, AVI or any other video format because MPKs are not videos, they only contain map data. However, MKV files are video files , so they can be converted to other video file formats with a free video converter.
Still can’t open the file?
It’s easy to misread another file’s extension as .MPK, even if the two formats are unrelated and can’t be used with the same software. If your file won’t open with the programs listed above, it’s most likely not really an MPK file.
Some file types that resemble MPK files include MPL, MPLS, and MPN. Another is KMP, which is a Korg Trinity/Triton Keymap file that can be opened with Awave Studio.
If you find that your file doesn’t actually use the .MPK file extension, research the file extension you’re using to learn more about the format, and hopefully find a valid program that can open, edit, or convert it.
