user: wapps. PHP Composer

[wapps]

My PHP Composr shows a dependency for phpmailer (which I need for sending emails).  When I look at my directory, I do not find any folders installed relating to phpmailer.  Am I missing something?

Let me try to clarify my issue.......  My PHP Composer shows phpmailer is installed.  Consequently, I was looking for signs of this being true by searching my Home Directory for installed files referencing phpMailer. Attached is a picture of my Home Directory.  The Vendor folder shown is a folder that I upload to my Home Director (not one created by PHP Composer).  I used this folder a home with my WAMP set up which enabled my to use phpMailer to send emails.  Shown in this folder is a folder "phpmailer".  I was expecting that this type of setup would have been generated by PHP Composer.  I can not find any reference to a folder in the Home Directory for phpmailer (except, of course, in the folder I uploaded).  Can someone explain this.  Is phpmailer working even though I can not see it?
