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

Description

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

Parameters

$filesarray|null

The list of files to use for filename comparisons.
Default null (to retrieve the list from the filesystem).

$dirstring

The directory for the new file.

$filenamestring

The proposed filename for the new file.

Source

$files = apply_filters( 'pre_wp_unique_filename_file_list', null, $dir, $filename );
