error loading text as variable from file and check it - batch-file

Question

this is some code it suppose to check for adb.exe in a location then if it exist will proceed to code if not will ask user to input location manually and check again if location is right will save the input in file "dontremoveoredit" to use it next time user open the bat file
the problem is if the file is empty or contain path it will crash the bat and close
