Add More Storage to Firestick (Fire OS 7)

Following this guide, you will discover how to add more storage to a Firestick or Fire TV running Fire OS 7. This includes, but is not limited to, Fire TV Stick Lite, Fire TV Stick 3rd Gen, Fire TV Stick 4K Max, and Fire TV Cube 2nd Gen.

The Amazon Firestick is undoubtedly the most popular streaming device on the market right now due to its low price and ability to jailbreak it with just a few simple tweaks. It’s a perfect streaming device for beginners as well as advanced users who wish to cut the cord.

However, just like any other streaming device, you must maintain your Firestick correctly to avoid issues. For instance, running out of storage is one such issue. But what can you do if you need more space? Adding an external USB storage device to your Firestick for more storage is entirely possible. See the videos for full details, or follow the written instructions below instead.

Getting Started

To add external USB storage to any Firestick or Fire TV, you must first prepare a few things.

  1. You will need to know which operating system your Firestick is running since adding more storage varies depending on the Fire OS.
  2. Decide how you will use the extra storage. Will you be using it as general, system, or mixed storage?
  3. Make sure the USB storage meets the requirements.
  4. You must have an OTG cable or adapter to attach the USB storage to the Firestick. But don’t plug it in yet.

If you are unsure or have not yet prepared these four things, read my guide on How to Increase Firestick Storage. Then, when you are ready to begin, return to this post.

Choose How to Use Firestick Storage

Any Firestick or Fire TV running Fire OS 7 can use any type of storage. In other words, you can attach and use USB storage for general, system or mixed storage. 

Refer to How to Increase Firestick Storage for more information on these different types of storage.

Use Additional Storage as General Storage

To use the USB storage as general storage, all you need to do is connect it. The system will handle everything for you. A menu will pop up, offering you a choice. Use the storage as External Storage (general storage) or Device Storage (system storage) to install more apps.

  1. Choose the External Storage option to use the USB drive as general storage.
  2. Then, select Yes to format the storage. 

You’ll be able to monitor how much of the storage space on the USB drive you’re using by going into the Firestick Settings.

  1. From the Home screen, select Settings.
  2. Then select My Fire TV.
  3. Highlight USB Drive to view the available external space.

There are several reasons why general storage can be helpful, including:

  • Access photos and videos stored on a USB drive connected to the Firestick. e best way to view media files on a USB drive would be to install a media player such as VLC or MX Player.
  • Share, save, explore, manage and transfer files between your Firestick internal and USB storage. I recommend using a file explorer application such as X-plore to do this. Find out how by taking a look a the following video.

Use Additional Storage as System Storage or Mixed Storage

Fire TV devices running Fire OS 7 recognise additional storage once you connect it. The system will handle formatting and partitioning of the USB storage for you. When you connect the USB storage, a menu will pop up, offering you a choice. Use the storage as External Storage (general storage) or Device Storage (system storage) to install more apps.

The system does not automatically support if you want to use USB storage as mixed storage. However, you can achieve this manually by entering a line of code. This code creates two partitions on the USB storage that allow part of it to be used as system storage and part as general storage. You can then install applications to the USB storage, and you’ll still be able to use and access part of the storage for sharing and accessing files. There are quite a few steps to this, but it shouldn’t take longer than 10 minutes, depending on your experience.

 

This guide will teach you how to do automatic formatting for all system storage and manual formatting for mixed storage. Continue to add more storage to your Fire OS 7 Firestick or Fire TV by following the step-by-step video tutorial. Or, if you’d prefer, follow the written instructions below instead. 

Add More System Storage (Fire OS 7)

Part 1 - How to Add System Storage to Firestick

  1. Power the Firestick up, then connect the USB storage to the Firestick using the OTG cable or adapter.
  2. A popup will appear on the screen for you to choose what to do with the USB device.
  3. Choose Device Storage.
  4. Then, select Yes to format the storage.

Once storage is formatted to additional device storage, you’ll no longer have access to the USB drive. You won’t be able to see and use it with a file explorer app such as X-plore, for example. 

Part 2 - Install and Move Apps to the Additional Firestick Storage

You can now use the USB storage to install more apps and most apps installed from here on will be installed on the USB drive.

Install Apps to Additional Firestick Storage

  4. Any app you install on the USB storage will display a USB icon.

If an application does not install to the USB storage, you can assume that the application developer has not set the permission. However, moving the app to USB storage is possible.

But, as the additional system storage has not been added via the system, you cannot use the system to move apps to the external storage. It must be done manually.

Manually Move Apps to the Firestick USB Storage (Fire OS 7)

You might be able to move an application manually to the USB storage if it did not install there by default. Moving an application can be done in one of two ways.

  1. Move the app without keeping any application data.
  2. Move the app and keep application data.

Application data refers to but is not limited to: usernames, passwords, settings and favourites.
