[Walter Roberson]

projectdir = 'path/to/place/with/15/folders';
dinfo = dir( fullfile(projectdir, '**', '*_out.png') );
fullnames = fullfile({dinfo.folder}, {dinfo.name});

fullnames will now be a cell array of character vectors naming all the png files that end with '_out' .

You did not give any information about what you might mean by "extract" for this purpose
