I am trying a create a simple flask app using Jupyter Notebook. The Tutorial I am following is suggesting me to create a directory - templates and put the html file inside it. When I tried to create the directory, it is showing " File already exists: templates ". But I am unable to find this directory and when I tried to access it programmatically, it is showing -

PermissionError: [WinError 5] Access is denied: 'C:\Users\Username\templates'
