        if (length < Math.Pow(1024, 1)) 
            return length + " B";               //lower than 1kb
        if (length < Math.Pow(1024, 2)) 
            return TrimSize(length, 1) + " KB"; //lower than 1mb
        if (length < Math.Pow(1024, 3)) 
            return TrimSize(length, 2) + " MB"; //lower than 1gb
        if (length < Math.Pow(1024, 4)) 
            return TrimSize(length, 3) + " GB"; //lower than 1tb

        return length + " TB";//return size in tb    
    }
