The safest answer is: don’t try to fix this by deleting unknown files on the card.

Best practice is to copy everything off the card to your computer or other storage, then format the card in the device you plan to use it with. Reusing the same card across different cameras without formatting can cause folder/file conflicts, since camera files are usually stored in the root-level DCIM folder and different devices may structure that differently.

If your main problem is Quik auto-launching, disable that behavior instead:

• Open GoPro Quik
• Click the settings/cog icon
• Turn off “Automatically launch Quik when camera is connected”

That stops Quik from monitoring inserted cards and trying to import from them.

So the practical solution is:

1. Back up the card contents
2. Format the card in the current camera/device
3. Disable Quik’s auto-launch if you don’t want it reacting to cards at all
