Canon CR3 RAW: recover after a quick format
Can deleted Canon CR3 originals be recovered after a quick format?
Short answer
Often, if no new frames were taken: formatting replaces the file-system records, but CR3 boxes usually stay until overwritten. Eject the card without a test shot. Scan it read-only, and if you shot RAW plus JPEG, check that both halves of each pair turn up before you ever format that card again.
The situation
The medium now has a new empty directory, while the previous deleted Canon CR3 originals is missing.
A format in the body is a bookkeeping action: it lays down new exFAT records and an empty DCIM tree. The CR3 boxes underneath survive until fresh frames land on them, so a card that reports itself as empty is usually still packed with data.
01 / Diagnose
Work out what actually disappeared
Formatting removes the map, not the territory. Every CR3 keeps its box layout, but nothing points at the files any more, and the camera has rebuilt its own image database as well. Recovered frames therefore arrive without their numbering, and RAW plus JPEG pairs must be reconnected by capture time rather than by name.
A quick format can replace file-system records without immediately overwriting every older content block. For Canon CR3 RAW, this matters because CR3 uses ISO-BMFF boxes for Canon RAW data, metadata and previews.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Eject the card before a single frame is taken, because a formatted card offers its whole surface to the next picture.
- 2
Note how many frames the card held, which body wrote them and whether C-RAW and paired JPEG were switched on.
- 3
Scan the card read-only from a reader and let the search cover the entire capacity, not only the newly written folders.
- 4
Export the found files to a separate drive and check, pair by pair, that each raw frame has the JPEG it should have.
Do not use the card for anything until the scan has finished, and do not format it a second time before that. A new burst fills the freed space quickly with large files, and each of them can take several frames with it for good.
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.
The body's image database, its folder numbers and any in-camera ratings went with the format. File Recovery Hero reads the exFAT card read-only, scans at no cost and exports once licensed to another drive; camera-side metadata and damaged frames are beyond it.
04 / Verify
Check the recovered content, not just its name
Sort by capture time rather than by numbering, which the format has taken away. A frame counts as recovered when it develops at full resolution in a converter that supports the model and its metadata matches the shoot, including body, lens and date.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can Canon exFAT card be recovered in this situation?+
A format in the body is a bookkeeping action: it lays down new exFAT records and an empty DCIM tree. The CR3 boxes underneath survive until fresh frames land on them, so a card that reports itself as empty is usually still packed with data. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not use the card for anything until the scan has finished, and do not format it a second time before that.
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?+
Sort by capture time rather than by numbering, which the format has taken away.
