## Download function
download_files(){

	files=( $FILEPATH_01 $FILEPATH_02 )

	#remove previous working directory
	rm -rf ./$1
	
	#create a working directory based on device id from adb devices output
	mkdir $1
	
	#move into working directory before pulling files
	cd ./$1

	#update files to make them globally readable then pull them
	for i in  "${files[@]}"
