Folder Server is a utility that allows you to create a local server that can be accessed from any device. This can be used for various purposes, such as hosting files, sharing them, or simply connecting to the server from your own device to view the content.

To begin with, select the folder that you want to share with your friends and click Start. Next, click on the "Access" tab, then enter the URL of the website that you want to access. You can also set the port number, and the app will start listening for incoming requests on that port.
