Review comment:
       I am thinking now all the clean file operations will become slow because of these size calculation code, which need to interact with the file system.
   
   so, can we can some option as `summary = false`, which won't do any new size calculation operation and clean the files faster ?? @akashrn5 , @QiangCai what you think ?
