I would suggest the use of a
disk quota.
Using a disk quota would limit the available space that
users could have used to store data. The New Technology File system (NTFS) has
several features like disk quotas to see which users are uploading the most
space. The windows interface Open
Computer Management is also another option that limits the number of users of a
shared folder.
