How to manage storage space on Fire TV and fix critically low on storage message

All Fire TV Sticks come with just 8GB of storage. Of that, you only have about 5GB usable space to install Apps, games and for caching. Soon, you’ll be running out of storage space if you install a lot of apps or stream a lot. Your Fire TV Stick will display a “critically low on storage” message when it runs out of usable space. In that event, you either have to reclaim existing storage or expand on it using external storage.

The best thing you should do is be aware of the storage limitations of your Fire TV Stick. So don’t install Apps you won’t use or Apps that are so big such as games. Also try not to save media on the Fire TV Stick itself. You can instead build a personal media server using a dedicated NAS drive and stream your content locally to your TV. But should you run out of space, here are some of the things you can do.

Uninstall unused apps

Not all the apps you install will usually be used. Sometimes, you just want to try out an app. Take an inventory of your existing apps and then uninstall those that are either not or less frequently used. To do that, go to Settings > Applications > Manage installed Applications. Click on an Application and select uninstall. Not all apps can be uninstalled especially Amazon’s built-in apps such as Amazon kids, Amazon live shopping, Amazon Music, Amazon Photos, Alexa Shopping, IMDB TV and Prime Video

Go to Settings > Applications
Select Manage Installed Applications
Select Uninstall

Clear Cache of frequently used Apps

Apps cache data to increase performance. Cache is temporal data that Apps create to quickly access frequently used functions. However, this cache can build up over time and cause your storage to get used up. You routinely might need to clear App cache. For instance, the Silk browser on my Fire TV Stick has 116MB of Cache. That’s a lot. You can easily clear cache and reclaim some storage space. Go to Settings > Applications > Manage installed Applications. Click on an Application and select clear Cache.

Select any App with lots of Cache
Clear Cache

Increase your storage with external flash disk or hard drive

OTG Cable

When you’ve run out of options to reclaim your existing storage, the best option is to simply add external storage. This is especially true if you tend to or want to download files such as videos and photos from your computer or the internet to the Fire TV Stick. You can do this using a File manager to transfer and manage files.

You’ll need an OTG cable or adapter. You can get one off Amazon for just $7 . For external storage, you can use USB-powered FAT 32 formatted flash disk or portable drive. You can get an affordable 64GB SanDisk Flask for just $11 or a bigger Seagate 2TB portable Hard drive for $60.

Keep in mind that only MicroSD cards can be used to expand storage for app installations(Looks like with the recent updates, you can install Apps to USB Drive too). The Flash disk plugs into the USB-A interface of the OTG cable while micro USB port plugs into the Fire TV. The other end of the OTG cable plugs to your power source which can either be a USB wall charger or one of your TV’s USB Ports. Make sure your external storage device is getting enough power, otherwise, it might not show up on Fire TV Stick.
