I would like to know how is it possible to create custom file located in extension root directory using JavaScript or Chrome API.

Extension root directory looks like:

• popup.html
• popup.js
• manifest.json
• icon.png

And I would like to create JSON file called test in that root directory.

So after that it should look like:

• popup.html
• popup.js
• manifest.json
• icon.png
• test.json

test.json should contain:

{
  "data": "123456789"
}

It is not duplicate, because that post is for File Dialog and I need to save it at fixed location and in extension folder. And as I said I want to create it, not download it.

• @SheshankS. No because it is for File Dialog, but I need to save it at fixed location and in extension folder. And as I said I want to create it, not download it. – tomsk Commented Jun 24, 2018 at 21:19

You can't. The extension directory cannot be used for storage -- its contents are not synchronized across machines, and the directory is replaced entirely when the extension is upgraded.

If you need to store data in a Chrome extension, use the chrome.storage API.
