Set disk quota limit per user

## to set disk quota limits per user

drName = 'C:' ## Here you can modify your drive name if you want to set drive 'E:'

threshold = '8000000000' ## warning level in bytes - 8GB set for warning

limit = '10000000000' ## limit level in bytes - 10GB set for limit

username = 'newuser' ## username of the specific user

mode = 'track' ## mode has 2 options - track / enforce; when we use track - disk limit can be crossed by the user but we notified when we use enforce user is blocked to cross his limit
