How to edit esp32-camera library

[brimas]

I want to edit some code in esp32-camera library locally on my PC. Specifically, I want to edit a file called ov2640.c in sensors directory to remove exposure limitation if statement. The problem is - I cannot find where the file is stored on my PC. I've been looking all over the installation directory of my Arduino IDE: C:\Users\<user-name>\AppData\Local\Arduino15\packages, with no success. I can only find some .h files related to ESP32. I installed the library in my Arduino IDE following this tutorial.
Does anyone know how can I modify the desired file?

I find the way how to edit library - you have to use ESP-IDF to upload the code when you can edit library localy
