default size of a newly created folder

Hi all,

     In linux how to create a directory with specified size, so that it can be used only up to the mentioned size.

  Actually my question is, whether we can do directory quota in linux.

mounting the directory in a partiton will do that, but do we have any other option than this.

Thanks&regards,
Anish
