Welcome to TNW Basics, a collection of tips, guides, and advice on how to easily get the most out of your gadgets, apps, and other stuff.

Google launched its file manager app over four years ago in 2017. At that time, it was called Files Go, and provided basic features such as folder management and file sharing between devices.

Over the years, the app has gained a lot of new functions with millions using it. One of the handy features in Google Files is Safe folder, which lets you secure your files behind a passcode. So even if someone has access to your phone, they can’t open those files without knowing that code.

Here’s how you can use it:

• Open the Google Files app on your Android phone.
• Tap on the Safe folder icon.
• When you set it up for the first time, you can set up a pin or a password for security.
• After that, you can select any files from existing folders, tap the three-dot menu on the top right corner, and select the “Move to Safe folder” option.

Once you do this, your files will be secure behind a passcode or a PIN. You can store sensitive images or documents behind a layer of security, so someone can’t easily access them. Now you can sleep peacefully.
