apply_filters( 'pre_wp_unique_filename_file_list', array|null $files, string $dir, string $filename )

Filters the file list used for calculating a unique filename for a newly added file.


Returning an array from the filter will effectively short-circuit retrieval from the filesystem and return the passed value instead.
