Been trying to put this on a ESP32

Hello there ! I've been tinkering with the Arduino IDE + ESP32 for the past week.

I tried the FSBrowser + AutoConnect from [here](https://github.com/Hieromon/AutoConnect/blob/master/examples/FSBrowser/FSBrowser.ino) but with no luck.

> Hardware:
> 
> Board: ESP32 DEVKIT1
> 
> Core Installation version: 1.0.1-git this one
> 
> IDE name: Arduino IDE
> 
> Flash Frequency: 80Mhz
> 
> PSRAM enabled: no
> 
> Upload Speed: 115200

This is my sketch:

My http://192.168.1.103/edit returns FileNotFound.

/list doesn't work like that. It works like this: http://192.168.1.103/list?dir=/ and it returns:

> [{"type":"file","name":"login.css"},{"type":"file","name":"index.html"},{"type":"file","name":"logo.png"},{"type":"file","name":"back-image.jpg"}]

As you can see I've uploaded 4 files into the ESP32's FlashMemory. I would like to "edit" them. Maybe delete one of them, or create a new file. I can't do that since /edit does nothing.

Do you have any idea ?
Thank you !
