This is a handy script for webmasters who have a lot of files in a directory.
All you need is to upload the file in the directory you wish, then view it in your browser and you'll get a nice listing of all files sorted by file type, so that you get an overview of your folder's contents.
You can choose to hide subfolders and hide hidden files (such as .htaccess).
The password is password by default. If you wish to change it, look for the line that says $password = 'password' ; and replace password with the password of your wish, leaving the starting and ending single quotes (') intact. If you wish to completely remove the password, just remove the whole line or enter a password that has less than 3 characters.
