Why does Dreamweaver save the same .php file twice?

  • I am creating a website on localhost (WAMP) as of now.
  • I have set up the testing server
  • the new php files that I create are saved in a sub-foldor of www folder specific for my website. [ C:\wamp64\www\mysite ]
  • Though, a duplicate of the file is saved outside the folder, in the www folder as well. [ C:\wamp64\www]
  • When I edit either file, both are edited.

I am confused as to why does this happen and how does this affect my website development process(Amateur developer).
