How to Expand Fire TV Stick 4K Internal Storage by Using a USB Flash Drive

It’s clear from sales and popularity alone that the vast majority of customers are extremely happy with Amazon’s range of digital streaming products, especially the newest Fire TV Stick 4K. Having said that, these devices certainly aren’t perfect. Various customers have pointed out a few ways that they could be improved. It’s mainly Amazon Fire TV not enough internal storage so you need to expand Fire TV Stick 4K internal storage.

Anyone who’s experienced with tech gadgets and devices will know that their advertised storage is often very different from their actual storage. The Fire TV Stick 4K external storage is no different. Although the device is advertised to have an internal storage of 8GB, due to its OS and pre-installed apps, users only have access to 5GB when using their Firestick. 

That’s 40% less storage so you need to add storage to Fire Stick memory expansion! And worse yet, that 5GB becomes even less when you install a handful of go-to apps, such as Netflix, BBC iPlayer, TV Player and more. But there’s a way around this.

Some users have found clever ways to expand Fire TV Stick 4K internal storage. They install applications on a separate Amazon Fire TV USB drive format that’s connected to the Fire TV Stick 4K. This is done as not to take up the Firestick’s own storage.

The following article will guide you through how this is done, and how you can increase Firestick storage to get the most out of it!

Choose a Good USB Drive

It’s worth noting, however, that this doesn’t work with all USB drives. Almost all USB 3.0 drivers worked just fine. But USB 2.0 and 1.0 had less of a success rate – though some of them did work.

Currently, the following information is visible:

  • Your Country:
  • Your City:
  • Your ISP:

If this is your real information, you need to use a VPN to protect your identity.

Expand Fire TV Stick 4K Internal Storage

Here are the steps you should follow:

Before you continue to follow the step-by-step guide explained below, make sure to have enabled the apps from the unknown sources on your Firestick.

1. Launch FileLinked on your Firestick and enter the WebSafetyTips FileLinked code – 11111111(eight ones).

WebSafetyTips store code on Filelinked

2. Scroll down until you find the Remote ADB Shell app. Click on it!

Install Remote ADB shell on Firestick via wst store

3. Go to INSTALL option.

Install Open Remote ADB Shell on Firestick
4. Launch Remote ADB Shell on your Firestick and click OPEN.
Open Remote ADB Shell on Firestick
5. Whilst on the screen of the Remote ADB app, input your Firestick IP address.

6. Type 55555 in the indicated box, and select ‘Next’.

7. Select ‘Connect’.
click connect
8. Select the option to, ‘Always allow from this computer’, and then select ‘OK’.

9. Click ‘OK’ to access the keyboard.
remote adb application
10. Enter into the keyboard sm list-disks, and select ‘Run’.
sm list
11. You’ll be able to see your disk’s name listen in the background. Make sure to remember what it’s named as you’ll need to use. By selecting ‘back’, you can exit the keyboard. This allows you to view the text.
disk name
12. After this, you’ll choose how to format the USB drive.

1. sm partition disk:8,0 mixed 50

If the name of the drive was ‘8,0’ then you can move to the next step with your Fire TV external hard drive. If not, you’ll be required to input the drive name before running the code. By choosing this method, you’ll be creating two partitions within your drive. For example, a 128GB 3.0 USB drive would be split equally, to make two partitions of 64GB each.

One of these partitions you will use for applications, whilst the other will store files. Many think this option is better suited (in comparison to ‘Option #2’ later in this article). There are a few reasons for that.

With this option, you can load both films, TV shows, and various other media from a computer. You play these files through one of the various media players available on the Firestick. You can move the media into the partition for storage so you can view it later. This is ideal for those with limited Internet access.

2. sm partition disk:8,0 private

option 2

In this case, you will format the entire disk for use as internal storage for running applications. This means you won’t be able to store media files for watching later. Whichever option you choose, type in the command you prefer, and select, ‘Run’.

13. After selecting the command, you’re likely to see that the USB drive at the bottom of the screen is removed.

14. The USB drive will soon connect again. You don’t need to worry.
normal connection
15. The next command will show you that the formatting has worked as it should have. Type in ‘df-h’, and then select ‘Run’.
run button
16. You’ll now be able to see each partition’s size, as well as the available space in each.

What is the Location of the App Installation?


If all has worked correctly, each application that’s installed from now on should be stored within the ‘dm-2’ partition of your USB drive. But some users find that this doesn’t happen, and that various apps they install don’t run through the USB drive when they expand Fire TV Stick 4K internal storage.

In order to find out exactly which applications are running from within the USB drive, go to: ‘Settings’, and then select, ‘Applications’. Select ‘Manage Installed Applications’, and whichever apps are running from the USB drive will be indicated by a USB icon to the side of them.

If the author or creator of the application doesn’t specifically support the app to be run from Fire TV Stick external storage source, then the app will by default run only from internal storage. In case you find an app you downloaded isn’t running from a Fire TV USB storage drive, this will mean that the app’s developer hasn’t done this from within their code.

There are some apps that definitely support Amazon Fire Stick external storage such as ES File Explorer, or Philo. Download and install these apps and see if the USB icon appears next to them. If there are still issues, it’s possible to use Remote ADB Shell to have these apps moved to a USB drive.


Although it might seem like a lot to get your head around, there are ways around Amazon’s restrictions. By utilizing one of these methods, you can expand Fire TV Stick 4K Internal Storage, so you can run all your favorite apps, media, and whatever else, with no limitations!

I have transferred most apps to the USB drive
They show ad USB on the app manager. BUT somehow the updates to apps that I have moved to the USB drive are filling up normal firestick memory to the point where there is no space for more updates. What do I do?

Hi Ben, go to settings ->my fire tv->dev options. Turn abd debugging off for about 15 or 20 seconds then turn it back on.
Also, I had better success using local host rather than my ip number.
Use this ip number
Best wishes

How can I get an app to download DIRECT to a jump drive (thats is working fine with apps,)

5 months ago

When i list the “packages” I can’t scroll through them to find what I’m looking for to move them to the USB drive. Also, how can I tell what the name of the app is? Obviously Disney + is DisneyPlus but there is a whole bunch of stuff that comes up that I have no idea what it is so I’m not sure if it’s an app I want to move or not. I tried re-downloading YouTube and Hallmark Movies Now, but they did not download to the flash drive. I also re-downloaded some other apps and they did Any… Read more »

I could not get past the partition stage. I would run df -h and it would hang up. With the drive plugged in it also created other issues with the Firestick. Could this be due to the particular USB drive?
