Being a coding illiterate I asked AI to write a batch file to periodically do some basic maintenance on my PC… I attach the result - it has been running on my PC [old hybrid 5xHDD 12Gb RAM Win10 blah blah blah] for months without problems, see attached 
it is a .bat file - somehow I cant load it but here is the content:
