if application:getDeviceInfo() == "Windows" then
	local lfs = require "lfs"
	-- go to user/pictures folder
	lfs.chdir(application:get("directory", "pictures"))
	-- check if "my_new_folder" directory exists in user/pictures folder
	local islfsdir = lfs.chdir(lfs.currentdir().."\\".."my_new_folder")
	if not islfsdir then
		-- if doesn't exist then create it and go to it
		lfs.mkdir(lfs.currentdir().."\\".."my_new_folder")
		lfs.chdir(lfs.currentdir().."\\".."my_new_folder")
	end
end
-- opens a window of the current lfs dir
os.execute("start "..lfs.currentdir())
