1. You need a variable route that will accept the a filename like @app.route('/<filename:filename>').
2. You then need to get the file with that name from your upload directory like file_path = os.path.join('UPLOAD_PATH', filename).
3. Then you need to read the contents of that file and pass it into your view.

with open(file_path) as file:
    content = file.read()

4. Then you can access it in your HTML file and display it.

<p>{{ content }}</p>

Here is a complete example of the route I described:

@app.route('/<filename:filename>')
def display_file(filename):
    file_path = os.path.join('UPLOAD_PATH', filename)
    with open(file_path) as file:
        content = file.read()
    return render_template('display_file.html', content=content)
