Run m-files from different paths error with reading .kml files.

I have several different maps containing functions, m-files and .kml-files. Now I want to read them all in a specified order, so I use a addpath(folderName) to load all folders. Then I use run(fileName) to run the desired m-files. My problem is that in one of the folders, there are a list of .kml-files which need to be loaded in order to execute the code in one of the m-files. I have added its directory in addpath, but still they can not be used. Why?

I would like to know is .kml file supports in MATLAB?
