Arduino plugin which packs sketch data folder into SPIFFS filesystem image, and uploads the image to ESP32 flash memory.

Installation

• Make sure you use one of the supported versions of Arduino IDE and have ESP32 core installed.
• Download the tool archive 
• In your Arduino sketchbook directory, create tools directory if it doesn't exist yet.
• Unpack the tool into tools directory (the path will look like <home_dir>/Arduino/tools/ESP32FS/tool/esp32fs.jar).
• Restart Arduino IDE.

On the OS X create the tools directory in ~/Documents/Arduino/ and unpack the files there

Usage

• Open a sketch (or create a new one and save it).

• Go to sketch directory (choose Sketch > Show Sketch Folder).

• Create a directory named data and any files you want in the file system there.

• Make sure you have selected a board, port, and closed Serial Monitor.

• Select Tools > ESP32 Sketch Data Upload menu item. This should start uploading the files into ESP32 flash file system.

  When done, IDE status bar will display SPIFFS Image Uploaded message. Might take a few minutes for large file system sizes.
