The file browsing feature is implemented using the ngx_http_autoindex_module module, with few optional configuration items.
location / {
    root /path/to/folder/;  
    autoindex on | off;   # Enable nginx directory browsing feature
    autoindex_exact_size on | off;   # File size format
    autoindex_localtime on | off;   # Whether the server uses local time
}
In practical use, it is recommended to use location in conjunction with routing access.
