get path to all files in a folder of images

how do i get the path to my image in a folder ?

% Directory
directory = 'C:\Datasets\nyu\train\';

% Filenames
image_rgb_filenames   = dir(strcat(directory,'image_02\','*.jpg'));
image_depth_filenames = dir(strcat(directory,'depth\','*.png'));

Because image_rgb_filenames(1).name returns me the name of the file, not the path to it with the name of the file.

% Directory
directory = 'C:\Datasets\nyu\train\';
img_dir = fullfile(directory, 'image_02');
depth_dir = fullfile(directory, 'depth');

image_rgb_info  = dir( fullfile(img_dir, '*.jpg'));
image_rgb_filenames = fullfile(img_dir, {image_rgb_info.name} );

image_depth_info = dir( fullfile(depth_dir, '*.png'));
image_depth_filenames = fullfile(depth_dir, {image_depth_info.name} );
