Suppose that you have installed XAMPP at c:\xampp This will mean you place your web files at C:\xampp\htdocs

Now you want to start developing your project, so what you could do is copy all your files to the C:\xampp\htdocs or create another folder
such as C:\xampp\htdocs\myproject

However, this is not always convenient so how do you create an alias, leaving your files where they are.

First, open the httpd.conf file, it’s located in this directory:
C:\Program Files\xampp\apache\conf

You can access this from the XAMPP control panel by clicking the “config” button.

Add these lines on the bottom of the httpd.conf file:

Alias /sources “c:/myproject”

Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order allow,deny
Allow from all
Require all granted

Note that in we must use “Forward Slash” or / in the folder definition

Restart XAMPP or stop and start Apache from the control panel.

Open your web browser and test it by go to http://localhost/myproject
