How to play files larger than 4GB off the Fire TV’s FAT32 USB storage in Kodi

Since the Amazon Fire TV will only accept FAT32 USB Drives, you can’t store files larger than 4GB on a drive that the Fire Tv can read. This poses a problem since many high definition video files are larger than 4GB in size. There is actually a simple solution to this problem. Kodi has the ability to detect split RAR files as a single video file. All you need to do is split your larger video files with a RAR utility before moving them to your USB drive. This guide will show you how to do that on both a Mac and Windows computer.


This method also works for playing files larger than 4GB off of a microSD card with the new 2nd-gen Fire TV. Just look for the files in the directory /storage/sdcard1

Windows Guide

  1. Download and install WinRAR.
  2. Right-Click the video file on your computer and select “Add to archive…”
  3. From the “Compression method” menu, select “Store“.
  4. From the “Split to volumes, size” menu, select “4,095MB (FAT32)“.
  5. Click “OK” and wait for the process to complete.
  6. When WinRAR is done, you will have 2 or more new files in the directory containing the original video file.
  7. Connect your FAT32 USB drive to your computer and move the new files (not the original video file) to a new folder on your USB drive. The folder’s name should be the same as the original video file.
  8. Connect your FAT32 USB drive to your Fire TV and launch Kodi. Open Files > extUSB and navigate to the new folder you just created.
  9. Open the folder and you’ll see that Kodi detects the split files as if it were the original large file. You can play the file as you would any other file in Kodi.

Mac Guide

  1. Download and install SimplyRAR.
  2. Launch SimplyRAR and drag the video file into the SimplyRAR window.
  3. From the “Compression Method” menu, select “Store“.
  4. Check the “Split archive” option on the right.
  5. From the “Split to volumes into” menu, select the “100Mb Files” option and click the “Create RAR” button at the top.
  6. Create a new folder to save the files into. Both the new folder and the files should have the same name as the original video file.
  7. When SimplyRAR is done, connect your FAT32 USB drive to your computer and move the new directory (not the original video file) to your USB drive.
  8. Connect your FAT32 USB drive to your Fire TV and launch Kodi. Open Files > extUSB and navigate to the new folder you just created.
  9. Open the folder and you’ll see that Kodi detects the split files as if it were the original large file. You can play the file as you would any other file in Kodi.

    Wouldn’t FTP file transfer allow for larger file size?

    • John says:

      The file size limitation is only for files stored on a FAT32 USB drive. If the files are stored elsewhere (like a network drive) then there is no file size limitation).

    Great article!

  4. Gryzor says:

    Wow, great tip, had no idea about that Kodi feature!

    One question, how are subtitles handled? Should they be included in the rar archive or remain separate?

  5. cxcorpx says:

    Is a lot of work, is waste time, I prefer the 51.4.3 where I mount the disk and put whatever I want or a nas hdd and Kodi I use folder mount for mount data and obb and I have the perfect TV box

    • Will G says:

      Stickmount still works with The only downside is I don’t believe you can move apps to the USB drive if you don’t format it as FAT 32.

  6. Marc says:

    Fantastic news for my unrooted Fire TV! It worked perfectly. Thank you for the great and straight-forward guide.

  7. N2Outlaw says:

    Does anyone know of a “External Powered USB HUB” that works on the latest “Prerooted Rom” (rbox) with “BootMenu” and that you don’t have to keep unplugging after reboot because it will get stuck on “Amazon” white logo if not unplugged from power. It’s just a pain.

    I got update fw on my fireTV then I connected 32g flash drive aftv can see it… I connect my old 250g HHD to see it will work or my surprise it work I can play movies mp4, avi and PDF files. Does update fw make all that?

  9. blahey says:

    I just finished doing this and now my USB drive is having issues. It won’t disconnect from my computer when I try to eject the drive and it is no longer connecting with the AFTV. Any suggestions? The error message on my PC said it was unable to eject the drive because a program was still running something from the drive. I shut down the computer and everything and still receive the message.

  10. Habenjero says:

    Isn’t a better solution to root it and enable it to read NTFS?

  11. Adam says:


    it is possible to connect a USB HHD true USB Power Port for the Stick version? I read that ADB communication over USB is possible. So it is not only a power USB port. I think over a active USB Hub shall the Fire TV Stick work together with a USB HDD? So there must be a possibility to enable USB support. Or not?

    try AVI Splitter.

  13. Immo says:

    Thanks for the guide! I can play these files fine when I go through “Video” and “Files”, but they don’t show up in the librarie under “Movies”. When I trie “Movie Information” Kodi says “No videeo files found in this path”. Any idea what I’m missing?

  14. HyperShrike says:

    To play video files over 4 GB (need ES File Xplorer and Kodi):

    Open ES File Explorer, then insert your NTFS-formatted USB thumb drive that has your video.
    You should see your USB drive appear.
    Ignore the “fat only supported” error message.
    Choose the USB drive on the left side of the screen, then find your video file in the USB folder on the right side.
    A “select” box will appear…choose Kodi (I get no sound using ES File Explorer’s built in video player).
    I have only tried this one time using an 8GB USB thumb drive and one 5.2GB mkv file,though smaller avi and mpg files play flawlessly also.
    Your mileage may vary.

    If anyone is looking at these instructions now, I have a small update. In the original screenshots in steps 3 and 4 it shows using RAR for the Archive Format. The current version of WinRAR for Windows, version 5, uses RAR5 by default, which Kodi won’t read. You need to select RAR4 as the Archive format. Here’s a screenshot.

  16. Paul says:

    I tried to split a 4.19gb file with SimplyRAR on a decent speed iMac and it was SOOO slow. Watching the folder while the split files were added was like watching a tortoise climb the stairs. I gave up.

    I can’t afford an hour+ to convert one movie.

    What idiot at Amazon thought using FAT32 would be ok for a TV box that can play 4K video. Any moron with a calculator can tell you a full length film is going to be big.

    My old WD Media box would read anything, even HFS (mac) format.

  17. Harry says:

    THANK YOU to Dan above for the RAR4 fix. Winrar had RAR5 pre selected in the add to archive menu and I didnt even know that was the issue. Would be great if the article was updated to reflect this change in Winrar.

  18. Chris says:

    Wish I read the comments before doing this multiple times; Thanks Dan for the heads up

    • Dan says:

      You’re welcome! I know the guide is almost 4 years old, but it might be worth an update.

      • kapD says:

        Hi Dan, Even after trying with the New WinRAR4 option and all the settings as per your snapshot,still Kodi is not detecting any video files.

        • CJ says:

          Seems the newer Kodi builds don’t have this feature built-in but it is available as an add-on called “RAR archive support” and it is working for me right now. To get it in Kodi:
          1. Click add-ons in the menu
          2. Press up and click the picture of the little box (install addon)
          3. Select Kodi Addon Resository
          4. Click Virtual Filesystem
          5. Click RAR archive support
          6. Click Install and wait for the download/install process to finish

          Note that I did have to close Kodi and re-open it in order for it to work. Also, I only tested RAR4 option but it is possible that this add-on supports the newer RAR5 option.

    I did everything according to this article from my Mac to my fat ms dos usb but it won’t detect

    This works great! I have been trying to figure how to play large files on a Firestick forever. You’re a genius.
