“File Is Too Large” Copying a 6GB Video to a PS5 USB Drive: How to Fix It

The error appears just as the copy is about to finish: the file is too large for the destination file system. Your 6GB video is fine, the USB drive has plenty of free space, and yet Windows refuses to copy it. It feels like the drive is broken, but it almost never is.

The real culprit is the drive’s format. Most USB drives ship formatted as FAT32, and FAT32 has a hard limit that no single file can exceed 4GB. Your video crosses that line, so the copy fails no matter how much total space is free.

Quick Answer

Back up everything on the USB drive, reformat it as exFAT, and copy the video again. exFAT has no 4GB file limit and is the format the PS5 supports for media playback and screenshots. Formatting erases the drive, so copy its contents somewhere safe first. If you cannot reformat, split the video into parts under 4GB or stream it to the console over your home network instead.

Why FAT32 Rejects Files Over 4GB

FAT32 dates back to the Windows 95 era, when a 4GB file was almost unthinkable. Its design stores a file’s size in a way that caps a single file at 4GB minus one byte. Modern video makes that limit trivial to hit: a few minutes of 4K phone footage, one GoPro clip, or a single movie file will all exceed it. The drive can hold 128GB in total and still reject your one 6GB file.

exFAT was created by Microsoft specifically to remove this limit for flash storage, and both the PS5 and Xbox fully support it for media. The PlayStation support pages list exFAT as the correct format for USB drives used with the console.

Fix 1: Reformat the Drive to exFAT

1. Back up the drive. Copy everything currently on the USB drive to a folder on your PC. Reformatting erases it completely.
2. Open the format tool. In File Explorer, right-click the USB drive and choose Format. On a Mac, open Disk Utility and select Erase.
3. Choose exFAT. Set the file system to exFAT and leave the allocation unit size on Default. Give the drive a short name like PS5MEDIA.
4. Format and copy again. Run the format, then copy the 6GB video. It will now complete without the error.
5. Test on the console. Plug the drive into the PS5, open the Media Gallery or a media app, and confirm the video plays before you delete your PC copy.

Fix 2: Split the File Instead

If the drive must stay FAT32 — for example it is shared with an older device that cannot read exFAT — split the video into chunks smaller than 4GB using a free archiving tool such as 7-Zip. Set the volume size to about 3,900MB so every part stays safely under the limit. The catch is playback: the PS5 cannot play split archives directly, so you would have to rejoin the parts on a PC before watching. Splitting is a transport solution, not a viewing solution.

Fix 3: Skip the Drive and Stream

A media server avoids the file system problem entirely. Install a DLNA server or Plex on your PC, keep the video on your computer, and play it on the PS5 over your home network with the console’s media player. This works well for a home movie library, though it depends on both devices being on and connected, which is why a properly formatted USB drive is still the simplest long-term answer.

One Warning About PS5 Extended Storage

Do not confuse a media drive with PS5 extended storage. When you plug a drive into a PS5 and format it as extended storage for games, the console encrypts it for that PS5 only, and your PC can no longer read it at all. A drive for videos and screenshots should be formatted as exFAT on your computer, never through the console’s game-storage setup.

Common Mistakes to Avoid

• Formatting before backing up. The format is instant and permanent. Move the drive’s current contents to your PC first.
• Compressing the video to squeeze under 4GB. Re-encoding a 6GB video down to size destroys quality. Reformatting the drive is faster and lossless.
• Choosing NTFS for console media. The PS5 does not read NTFS drives for media playback. exFAT is the correct choice.
• Assuming the drive is faulty. The error message is about the file system, not the hardware. The same drive works perfectly once formatted as exFAT.

Check the Drive’s Current Format Before You Blame It

If you are not sure how the USB drive is formatted, check before assuming. On Windows, right-click the drive in File Explorer and open Properties: the file system is listed at the top of the General tab. FAT32 confirms the diagnosis instantly. On a Mac, select the drive in Disk Utility and the format is shown under its name. While you are looking, note the drive’s true capacity too — a drive that reports a size wildly larger than what you paid for deserves suspicion of a different kind.

After the Copy: Will the PS5 Actually Play It?

Getting the file onto the drive is only half the journey; the PS5’s media player is pickier than a PC about what it plays. It handles common combinations well — MP4 files with H.264 or H.265 video and AAC audio are the safe centre ground. Videos in unusual containers or with exotic audio tracks (some MKV files, or clips with DTS audio) may copy perfectly and then refuse to play, or play silently. If a file will not play after a successful copy, the fix is conversion, not another copy: a free tool like HandBrake can re-wrap or re-encode the video into a console-friendly MP4 on your PC. Test playback with one short clip before converting an entire season.

Also organise as you go: the PS5 browses USB media by folder, so films dropped into a single Video folder are far easier to find on the console than hundreds of loose files in the drive’s root. And keep the PC original until you have watched the file play on the console itself — the copy being present is not the same as the copy working.

Conclusion

The “file is too large” error is a 1990s limit colliding with modern video sizes. Back up the drive, format it as exFAT, and the same 6GB file copies without complaint and plays on your PS5. Keep the drive dedicated to console media, and you will never see the error again.

Frequently Asked Questions

Why does the error happen when the drive has 100GB free?

Because the limit is per file, not per drive. FAT32 cannot store any single file larger than 4GB, even if the drive is almost empty.

Will exFAT work for PS5 screenshots and game clips too?

Yes. When you export screenshots and clips from the PS5 to USB, the console expects an exFAT (or FAT32) drive, and exFAT avoids size limits on long 4K recordings.

Does formatting to exFAT erase everything?

Yes, completely. Always copy the drive’s contents to your PC first, format, then copy back what you still need alongside the new video.

Can I convert FAT32 to exFAT without formatting?

No. Windows offers a no-loss conversion only from FAT32 to NTFS, which the PS5 cannot read for media. Backing up and reformatting is the safe route.

My video is exactly 4GB. Will it copy to FAT32?

Only if it is under 4GB minus one byte — in practice, files shown as “4.00 GB” in Windows are usually slightly over the real limit and will fail. Use exFAT and stop worrying about the boundary.
