For create a file in append mode ,we need to use this constructor.

> ```
> StreamWriter file = new  StreamWriter(".../Text.txt", bool append);    file.WriteLine("your text");

if file are exist in specified path otherwise it will created a new one as well as it will start write in append mode(if bool append is true otherwise file will be override ).\
