An app that can scan archive files and delete them I'm looking for an app that have this features:


Scan all archive files inside a directory (say, Downloads folder)
Determine whether if I have already extracted the archive files or not (inside the directory)
If I have already extracted the archive files, then delete them (archive files). If I'm not extracted them yet, keep it inside the directory


Any recommendations?
To automate things like that, I use Hazel (paid software, 29$).


  Hazel watches whatever folders you tell it to, automatically
  organizing your files according to the rules you create. It features a
  rule interface similar to that of Apple Mail so you should feel right
  at home. Have Hazel move files around based on name, date, type, what
  site/email address it came from (Safari and Mail only) and much more.
  Automatically put your music in your Music folder, movies in Movies.
  Keep your downloads off the desktop and put them where they are
  supposed to be.
