Filter collection using like and wildcard

I need to get all files which starts with desired letter, I'm trying to use a ->where filter adding 'like' as operator but wildcards doesn't work.

        $files = File::files(storage_path($id_files));
        $files = collect($files);
        $files->transform(function ($item, $key){
            $item->public_filename = $item->getFilename();
            return $item;
        });

This is our target data, I need to create a public_filename field to apply filters to. Our files (dd($files)):

   Collection {#503 ▼

      file: true

    }
  ]
}

What I'm trying:

dd($files->where('public_filename','like','t%')); // 0 results

dd($files->where('public_filename','like','txt.txt')); //If I ommit wildcard and look for full name it retrieves correct file

So our target is:

dd($files->where('public_filename','like','t%')); // 1 result

Any idea? Could we use wildcards to filter a collection by using a like operator? Thank you guys!
