public static void Main(string[] args)
        {
                       // BAD CODE, DON'T TRY IT !

            byte[] bin;
            string inputFilename = @"E:\Goods_Indonesia.txt";
            using (FileStream fs = new FileStream(inputFilename,FileMode.Open))
            using (BinaryReader br = new BinaryReader(fs))
            {
                bin = br.ReadBytes(Convert.ToInt32(fs.Length));
            }

            for (var i = 0; i < bin.Length; i += 2048)
            {
                Unshift(bin, i, 3);
            }

            Process.GetCurrentProcess().WaitForExit();
        }

       public static void Unshift(byte[] buffer, int start, int bits)
       {
           int length = buffer.Length - start;
           byte last = buffer[length - 1];
           byte current;

           for (int i = length - 1; (i & 0x80000000) == 0; i--)
           {
               if (i <= 0)
               {
                   current = last;
               }
               else
               {
                   current = buffer[i - 1];
               }
               buffer[i] = (byte)(current << (8 - bits) | buffer[i] >> bits);
           }
              Console.WriteLine(Encoding.UTF8.GetString(buffer));
       }

hoping it would be faster than the last one, but same result and most of the times it freeze my computer if i open bigger file, googling for hours and can't find an answer (wrong keyword perhaps)

any advice is greatly appreciated,
