With the Share It app, you can share various types of files with any other device that is connected to the same Wi-Fi network or using Bluetooth. 

Once you open the app, you will see the shared tab on the top-left side of the screen. On the other side of the screen, you will see the file selector tab. You will be able to select a file or a folder that you want to share. Once you make your choice, the app will automatically share the file that you have chosen.

You will also be able to see the comments on each file that is shared.
