pre_recurse_dirsize filter-hook . WP 5.6.0

Filters the amount of storage space used by one directory and all its children, in megabytes.

Return the actual used space to short-circuit the recursive PHP file size calculation and use something else, like a CDN API or native operating system tools for better performance.

function filter_function_name_2022( $space_used, $directory, $exclude, $max_execution_time, $directory_cache ){
	// filter...
