For each textfile, write blogpost. No DB.

I have the code for making a single post:
string title; string post; using (StreamReader streamreader = File.OpenText(MapPath(@"Blog_Posts\Post.txt"))) {     title = streamreader.ReadLine();     post = streamreader.ReadToEnd();     title_lbl.Text = title;     post_lbl.Text = post; }
The problem is when I want to make more posts. I do not have the possibility to use databases.
Any suggestions is appreciated, thank you.
