How to make a portable (from one executable file) application for PC using html/css/js?

Question

Node.js

Greetings. The task is to make a file manager on html, css, js from one executable file (.exe for Windows). Since the scripts running inside the browser do not have access to the file system, I thought to do it on electron js. But it cannot pack everything into 1 executable file (I did not find such a manual). Only packaging in the installer.
I ask for advice, what tools to use to accomplish this task? Preferably multi-platform...

Answer 1

Make a fake filesystem through Enigma Virtualbox. Read more ( https://github.com/electron/electron/issues/914 )

Answer 2

There is an Electron-builder for building a project into one exe (well, or whatever you need there). And for processing the FS system, you need to configure the build'er (I don't know for sure now).
