Canon R6: movie files exceeding 4GB (SDHC vs SDXC)
Canon documents 4GB behavior: SDHC/FAT32 splits into multiple files, SDXC/exFAT can save as a single file.

Direct answer
- SDHC (FAT32): files split over 4GB into multiple movie files.
- SDXC (exFAT): movies can be saved as a single file even if they exceed 4GB.
How to avoid 4GB splits (steps)
- Use an SDXC card (not SDHC).
- Insert the card, press MENU.
- Go to Setup (wrench) tab → Format card.
- Format the SDXC card in-camera (this sets it up for exFAT behavior).
- Record as normal, your long take can stay as a single file beyond 4GB.
What it means in practice
If you want long recordings to stay as one file, use SDXC and format it in-camera. If you’re using SDHC, splitting is normal and expected.
