	I've changed the ESP32 partition table definition and created a new binary file. How do I get the compiler to use it?

	File attached. I'm trying to increase the memory available to my software and I don't need OTA capability so I've used the huge_app.csv partition table. There may be a better way of doing this... I'm guessing this is the line in question from the log file: s/gen_esp32part.exe" -q s/partitions/default.csv" lease/BLETest.ino.partitions.bin" So can I change that or do I need to rename the huge_app.csv file as default.csv?

	Yes you can override the partion file in two ways however you should ensure you have reviewed the "Partion Schemes" on the vMicro menu. Those are the different schemes that ship with the board code. Keep in mind that what works for the Arduino IDE will also work for Visual Micro. This article shows how to use a custom esp32 partion Plus you can use a board.txt in the local visual micro project to override any properties. In this case the properties will be set without board prefix like this:- //board.txt Code build.partitions=MyCustomPartionFileName

	Which bit of the vMicro menu is it under as I don't appear to have that option? Is it something to do with this? https://github.com/espressif/arduino-esp32/issues/1906 as that's the board I have.

	That is why the Partition Schemes are missing from the vMicro menu for your board, and you could add them in manually as noted on that thread. It may be worth adding a fresh request to that repository to get this updated in the core.
