 - On Arduino IDE menu: *Tools > Partition Scheme* select one with FAT partition
-- The usable size of FAT partition is reduced with 1 sector of 4096 bytes (0x1000) to resolve wear leveling space requirement
-- For same reason, the image file is flashed with +4096 bytes (0x1000) offset of partition address csv table entry

 - To flash the data folder as FAT partition by network port (uses espota), replace your esp32-core Update library with the [modified files here](https://github.com/lorol/arduino-esp32fatfs-plugin/tree/master/extra/esp32-modified-Update-lib-ffat-espota.zip)
 - You may need to decrease **maxOpenFiles** at FFat.begin() of your sketch , [see this note](http://marc.merlins.org/perso/arduino/post_2019-03-30_Using-FatFS-FFat-on-ESP32-Flash-With-Arduino.html) 
 >The FFAT module uses 8KB plus 4KB per concurrent file that can be opened. By default, it allows 10 files to be opened, which means it uses 48KB. IF you want to reduce its memory use, you can tell it to only support one file, and you will save 36KB, leaving you with only 12KB used.

 - 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.

+## Quick build on Win:
+
+- Install Java JDK 
+- Find the path of javac.exe and jar.exe
+- Edit make_win.bat accordingly
+- Copy files **arduino-core.jar , commons-codec-1.7.jar , pde.jar**  from your Arduino IDE installation to the folder where is located **make_win.bat**
+- Run **make_win.bat**
+- Find the **build jar** in /bin directory
