Copy the metadata into a folder to send to people

Illidanstorm

So I've watched this tutorial https://www.daz3d.com/package-your-props-for-sale and now managed to make props to use on other computers. If it's for example a cola bottle I put the textures inside runtime / textures / ME and the obj into runtime / geometries / ME.
Then I save it as a figure prop asset and put the data / ME folder inside the zip file... so far so good.

But then when I load it into another PC there is no metadata for the smart content. The item looks like this on the PC I made it on, but on other PC's it doesn't have this Green sign "Prop" but I want that. Which step did I miss?
