Hi @gigetto1982. Arduino IDE doesn't support working with files that have the .txt file extension. If you want to add and edit a file with that extension you will need to use a standard text editor.

However, Arduino IDE does support working with files that have the .md file extension. This file extension is used for files written in the Markdown markup language. This markup language is very frequently used for the documentation files of open source software projects. We even use it here on Arduino Forum.

If you would like to learn about how to use Markdown, there is a nice reference here:
