ESP File Manager for NodeMCU (ESP32)
Branched to support ESP32.
[Minor edit, cosmetic only (help file.)]
See the aptly named help.html for complete setup and usage details.
Edit cfg.lua to determine whether it will initialize WiFi as a station (default) or AP, determined by the value of cfg.Mode. If you leave it in station mode you'll still need to edit cfg.lua to set the SSID and password for your WiFi. (Station mode automatically instantiates AP mode, so both work at the same time, IP for the AP is the default,192.168.4.1, to change that it must be confifured for AP mode only.)
The default file is index.html, the one provided merely loads files.html. Just browse to the IP address of your ESP8266 to load it into your browser.
