I am currently attempting to add the zipped file oscommerce_quantunqgwdbe_1_2_1
to the file manager level where checkout_success.php exists.

I'm new to this and do not know how to get it there and unzip it. Sorry.

The checkout_success.php file is located in the main directory for your store, wherever you installed it to. You will want to unzip the file on your home computer first before moving it to your site.

Before you do anything with your site, check for a readme file with your modification. Most authors of contributions add some notes as to what files are being modified/replaced. If you simply replace files that you have made changes to for other modifications your store may not work as you expect it to. Many modifications for OsCommerce involve multiple file changes so it's a good idea to back up your site first.

Once you've got the file unzipped and determined what steps you need to take to update your site then you can upload using CPanel or an FTP program of your choice.
