Some rules to organize your work files

  1. Users are strictly required to save their work files under their home directory
  2. No user is allowed to write any files onto /tmp, this directory is reversed for system files swapping
  3. All files under /tmp will be removed without prior acknowledgement<
  4. For those who need a larger swapping area, they can save their work files on /public temporarily
