When you save the file it confirm to remove the file, if the filesize is 0 byte.

vim-hykw-removeFileIf0Byte

When you save the file, if the filesize is 0 byte, it confirm to REMOVE the file(also close the buffer)

It's too small snippets, I writes it in .vim file like below. When you answer y, it just removes both the file and buffer.

augroup hykw_removeFile
  autocmd!
  autocmd BufWritePost * call s:Hykw_removeFileIf0Byte()
augroup END

function! s:Hykw_removeFileIf0Byte()
  let filename = expand('%:p')
  if getfsize(filename) > 0
    " do nothing
    return
  endif

  let msg = printf("\n%s is empty, remove?(y/N)", filename)
  if input(msg) == 'y'
    call delete(filename)
    bdelete
  endif
endfunction
