Setting quota?

Add public int QuotaSize; //this is in MegaByte
Add public string QuotaSetFolder;
Also add in constructor as well, and do something like QuotaSetFolder = BaseUrl;

        public int QuotaSize
        {
            get { return Settings.ConfigFile.Current.QuotaSize; }
        }

        public string QuotaSetFolder
        {
            get { return Settings.ConfigFile.Current.QuotaSetFolder; }
        }

        if ((oFile.ContentLength / 1024 / 1024) + GetDirSize(new System.IO.DirectoryInfo(Config.Current.QuotaSetFolder)) > Config.Current.QuotaSize)
                            ConnectorException.Throw( Errors.ExceedsQuota );

        public long GetDirSize(System.IO.DirectoryInfo dirinfo)
        {
            long totalSize = 0;

            foreach (System.IO.FileInfo fileinfo in dirinfo.GetFiles())
                totalSize += fileinfo.Length / 1024 / 1024; //in MB

            foreach (System.IO.DirectoryInfo dirinfosub in dirinfo.GetDirectories())
                totalSize += GetDirSize(dirinfosub);

            return totalSize;
        }

500 : 'The file browser is disabled for security reasons. Please contact your system administrator and check the CKFinder configuration file.',
501 : 'The thumbnails support is disabled.',
550 : 'Exceeds Quota'
},

   public override void SetConfig()
   {
      QuotaSize = 1;
      QuotaSetFolder = @"C:\Inetpub\wwwroot";
