How to add assets for Windows Phone 8.1 (Universal), cocos2d-x v 3.7?

I copied all my asset folders into the “Assets” directory.
In visual studio 2013 I click on the assets folder in the solution folder → Add->Existing Item…, and then I choose each of the files.

I then clicked on each file-> Properties, and ensured that for “All Configurations”, “Excluded from Build” is set to “No”, “Content” is “Yes”, and I set the Item type.

I try to read files like:

    std::string leveldata = FileUtils::getInstance()->getStringFromFile("levels.lvl");

But I get a message in the log:

cocos2d: fullPathForFilename: No file found at levels.lvl. Possible missing file.
Get data from file(levels.lvl) failed!

My leveldata string is blank because it can’t find the file.

My folder structure is:

Assets–>data–>levels.lvl

(Assets is the folder created automatically by the cocos tool)

How do I get this to work ?

Figured it out. Ignore the assets directory, and just place your stuff in the resources directory.
