You can protect a file in two ways:
- Open a file with Prot-On and it will be protected automatically. Long press on the file and select “Open to Prot-On” or “Share Prot-On”.
- You can take a photo or record video or audio directly from the Prot-On application and it will protect the file automatically for you. You can also go to the Gallery to protect a file that you already have on your Smartphone.
