Canon CR3 recovery after an in-camera format
Can Canon CR3 files be recovered after formatting?
Short answer
Often yes after the standard in-camera format, unless low-level formatting was selected and as long as you have not shot again. The format rewrites the directory, while older CR3 data in its ISO-BMFF structure stays until new images reuse the space. Take no test shot, scan read-only for CR3 and accept only complete containers.
The situation
CR3 originals disappeared after the camera formatted the card.
A standard format in a Canon body rewrites the directory and leaves the older image data in place, which is why CR3 files are often still reachable afterwards. Low-level formatting is the exception. What settles the case in practice is whether the card has been used for new shots since.
01 / Diagnose
Work out what actually disappeared
CR3 files use an ISO-BMFF container, the same box structure as MP4, so they can be identified by their own header instead of by a directory entry. An in-camera quick format creates a fresh allocation bitmap and an empty DCIM tree, while the old image extents stay untouched until new photos claim them. A low-level format writes across the card and leaves nothing behind.
A quick format can replace directory metadata while older ISO-BMFF CR3 extents remain until reused.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Put the card away at once and shoot with a different one, because a single test frame can land on a CR3 you still want.
- 2
Recall which format option was used in the menu, since the low-level variant runs considerably longer and overwrites the whole card.
- 3
Scan the exFAT volume read-only for CR3 specifically, so results are not buried under thousands of thumbnail fragments.
- 4
Export everything to a computer disk and open each file in a converter before the card goes back into rotation.
Do not take a test photo to confirm the card still works, do not format it again, and do not let the camera write a fresh folder structure onto it. Each of those can consume the clusters that still carry your CR3 image data.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
After a low-level format, or once new shots have filled the card, the image data is gone and no scan returns it. File Recovery Hero reads exFAT, NTFS and FAT volumes read-only and does not repair a CR3 whose container came back incomplete.
04 / Verify
Check the recovered content, not just its name
A recovered CR3 must open at full resolution in a converter that supports the model, with usable exposure and lens data. A file that shows only its embedded preview, or that stops decoding partway through, has lost boxes from its container and counts as incomplete.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can formatted Canon exFAT card be recovered in this situation?+
A standard format in a Canon body rewrites the directory and leaves the older image data in place, which is why CR3 files are often still reachable afterwards. Low-level formatting is the exception. What settles the case in practice is whether the card has been used for new shots since. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not take a test photo to confirm the card still works, do not format it again, and do not let the camera write a fresh folder structure onto it.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
A recovered CR3 must open at full resolution in a converter that supports the model, with usable exposure and lens data.
