Qustion: Even though I did these changes for the huge_app, arduino IDE still says that the sketch is too large when uploading.

Answer:
Please use the following file when modifying the partition.
This is the files we've modified; we already set to the maximum size.

Please simply place the files in the corresponding location.

    I am having the same problem, when compiling the example code (with the recommended libraries) I even removed unnecessary code (LED strip and Wifi code) and the code is compiling to almost twice the memory size of the ESP32. (Sketch uses 5951649 bytes (189%) of program storage space. Maximum is 3145728 bytes)

    Will these files help me, and what is the corresponding location? I am running Arduino IDE 1.8.19
