Answer 1

In these cases first you need get files of directory like following:
$dir = './FILE_FOLDER_NAME';
$files = scandir($dir);
unset($files[0]);
unset($files[1]);
Why we used unset, these code remove . and .. from $files variable and you have just file names.
Now you can show files with this approach:
foreach($files as $key => $value):
$path_info = pathinfo($value); //RETURN FILE EXTENTION
?>
<a href="DIRECTORY_PATH<?php echo $value; ?>" target="_blank"><?php echo $value; ?>
<?php
endforeach;
If you want to delete a file can add new button to your foreach like this:
<button href="PHPSAMPLEFILE.PHP?file=<?php echo base64_encode ($value); ?>"><?php echo 'DELETE'; ?></button>
and in your PHP file:
$file = base64_decode($_GET['file']);
$path = './DIRECTORY_PATH/'.$file;
unlink($path);
