Simple Question about file locations

[someonesusername]

Is there any documentation about the file locations for Wordpress files, for example I found out that the wp-config.php file in the root of the wp install does nothing at all, I knew that there was another overruling file somewhere but forgot it’s location.

These are the strings that I’ve been looking for;

max_allowed_packet
WP Memory Usage
WP Memory Limit
PHP Memory WP-Limit
PHP Memory Server-Limit
PHP Memory WP-Usage
PHP Memory Server-Usage
PHP Max Upload Size (WP)

Just reply the one YUKNOW

I had an issue with file size
413 Request Entity Too Large

I solved this by changing:

/etc/nginx/nginx.conf

http {
(…)
#set client body size to 20M
client_max_body_size 20M;

/etc/nginx/sites-available/yourwebsite.conf

server {
#set client body size to 20M
client_max_body_size 20M;
