Map data on an SD card and map preload
Customization and runtime configuration > Customizations for maps
July 22, 2014

Applies to: Windows Phone hardware development

Map data is used by the Maps application and the map control for third-party applications. OEMs can choose to store this data on an SD card, which provides the advantage of saving internal memory space for user data and allows the user to download more offline map data. Microsoft recommends enabling the UseExternalStorage setting on phones with less than 8 GB of user storage and has an SD card slot.

UseExternalStorage can be used whether or not an SD card with preloaded map data is included on the phone. If no SD card is present, the system uses internal storage until an SD card is available and then automatically switches to using an SD card for map storage. The user's ability to download map regions is disabled until an SD card is available.

Important note
SD card performance can affect the quality of the Maps experience when maps are stored on the SD card. When an SD card is used, Microsoft recommends that OEMs test the Maps experience and the speed of map downloads with the specific SD card part that will be used on retail phones to determine if performance is satisfactory.

Sample: UseExternalStorage
Use the customization samples

Constraints: None
Microsoft recommends enabling UseExternalStorage on phones with less than 8 GB of user storage and has an SD card slot.

Create a customization answer file using the contents shown in the following code sample or use the sample UseExternalStorage.xml file.

Copy code
<?xml version="1.0" encoding="utf-8" ?>
<ImageCustomizations xmlns=""
Description="Use to preload map data on an SD card."


<!-- Enable external storage for map data on an SD card -->
<Settings Path="Maps/Storage">
<Setting Name="UseExternalStorage" Value="" />


Specify an Owner.

Set the Value to one of the following:



0 or No

Do not store map regions on an SD card.

1 or Yes

Store map regions on an SD card.

If including an SD card with the device, add the preloaded map data to the SD card. Unzip the appropriate map variant data package and copy the “diskcache” folder onto the SD card under the d:\MapData directory.

When unzipping the appropriate map variant data package, you must use a file compression/decompression utility that preserves the file attributes and timestamps. If the utility does not preserve this information, the map(s) will be treated as invalid by the OS.

Flash a build that contains this customization on a phone.

Launch the Maps application and open Settings from the application bar.

Click on the Download Maps button and verify that the expected region displays under downloaded maps.

what says this ? i don't check what we have to do to use this solution.

Use the customization samples
Customization and runtime configuration
July 22, 2014

Applies to: Windows Phone hardware development

Partners can download and use the sample customization answer files to get started with customizing Windows Phone 8.1.

To obtain the sample customization answer files
Download the file from the Connect site. This .zip contains sample customization answer files for the majority of customizations documented in this section.

For a list of all customization samples, see Customization samples index.

To use the sample customization answer files and build a custom phone image
Ensure that you have an updated kit installation, and that you can build a phone image using it and flash that image to your engineering device.

If you have not already done so, create a folder for your packages in %WPDKCONTENTROOT%. Name the folder OEMCustomizationPackages or give it a similar name so you know this folder contains all your customizations. Note that this folder can include many subfolders.

Copy a sample customization folder from to the OEMCustomizationPackages folder.

Open the sample XML customization answer file and modify it to optionally change the values from the sample customization answer file and provide any required values:

The values used in the root customization answer file (or the one you specify as the input customization answer file during ImgGen.cmd or CustomizationGen.cmd in Step 6) is used to determine the package owner so it is important to provide these required values.




OwnerType (in the customization samples this is typically already set to 'OEM').

Any files, assets, or other settings specific to the customization. See the corresponding topic in the Customization and runtime configuration section of the documentation for more information about what to change and how.

You must also update or replace any additional files included in the sample folder. Instructions are provided in the customization topic in the documentation.

Note that you’ll be using the customization answer file as one of the inputs when building your customization package or OS image.

Open a Developer Command Prompt for VS2013 window (if you have installed Visual Studio 2013) or a Command Prompt window (if you have not installed Visual Studio 2013) as an administrator. Configure the environment variables in this window as described in the Set up environment variables section of Preparing for Windows Phone development.

Depending on what you want to do, you can use the customization answer file to create a package containing your customization(s) or use the answer file as one of the inputs to create an OS image.

To use the customization answer file to generate a package without building an OS image, see Generating customization packages without creating an image in Building a phone image using ImgGen.cmd to find out how to use CustomizationGen.cmd.

To build an image as an .ffu file using the customization answer file as one of the inputs, see Using ImgGen.cmd to generate the image in Building a phone image using ImgGen.cmd to find out how to use ImgGen.cmd.

Flash the .ffu file to a phone. For more information, see Use the flashing tools provided by Microsoft.

See the Testing steps section in the corresponding customization topic to verify that the customization has been configured properly.
