First Steps > View Localhost
Your default host for MAMP PRO is “localhost”. The files for localhost are initially located in the “C:\MAMP\htdocs” folder. Press “Open” located to the right of the “Host Name” text box to open up the localhost in a web browser.
If you are upgrading from MAMP Free, and you used several sub folders under “C:\MAMP\htdocs” to create several hosts, you then need to check the “index” checkbox to see you directory structure of “C:\MAMP\htdocs”. Check this checkbox, restart your servers and you will see your directory structure.
