What to do with extra files in folder

When I download the data update, it contains a folder with .xml files which I have moved to the editor data folder. However, there are 5 .fmf files in the download which I don't know what to do with because it doesn't say anything about them in the installation instructions. Can someone tell me what these files do and what I need to do with them?

Place them all into the editor data folder as well
