Canon CR2 RAW: recover after deletion
How can I recover deleted Canon CR2 originals after deletion?
Short answer
Yes, often, as long as the Canon card has not been used again. CR2 is TIFF-based and carries an embedded preview, so a thumbnail can appear even when sensor data is incomplete. Remove the card, scan read-only for CR2 plus JPEG if you shot both, and develop each recovered file fully in a RAW converter.
The situation
deleted Canon CR2 originals no longer appears in its recording folder even though the storage device is still detected.
Deleting on the camera clears the entry, not the raw data. CR2 files stay in their blocks and remain recognisable because the format is TIFF-based, yet the embedded preview makes results look better than they are, so every file has to be developed before it counts.
01 / Diagnose
Work out what actually disappeared
When the Canon body deletes a picture, or the folder is erased on a computer, the exFAT entry is released and the clusters become free. A CR2 file combines a TIFF-style directory, an embedded JPEG preview and the sensor data. Those parts lie at different offsets, which is why a partly reused frame can still display its preview.
Deletion can release a directory reference before later writes reuse every block that belonged to the file. For Canon CR2 RAW, this matters because CR2 is TIFF-based and can contain an embedded preview that survives even when sensor data is incomplete.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Switch the camera off and take the card out before the next shot places new data on the clusters that were just freed.
- 2
Note the Canon body, whether RAW plus JPEG was active and how many frames the folder held, so pairs can be matched later.
- 3
Read the card through a card reader with a read-only scan for CR2, and include JPEG when the camera wrote both files.
- 4
Export the results to another drive and develop each CR2 in a RAW converter instead of judging them from a thumbnail grid.
Do not put the card back into the camera to inspect the folder, and do not let the body rebuild its picture index. One new frame is several dozen megabytes and can cover a handful of raw files, including those that were still complete.
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.
Frames whose clusters have already been reused cannot be assembled again, and a broken CR2 is not repaired here. File Recovery Hero reads the Canon card in exFAT read-only, scans free of charge and asks 50 EUR once for exporting to another drive.
04 / Verify
Check the recovered content, not just its name
A CR2 is usable when a RAW converter opens it at full sensor resolution and the picture develops without stripes or a grey lower half. Where the camera also wrote JPEG, that JPEG shows what the frame should look like and exposes a raw file that only partly survived.
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?+
Deleting on the camera clears the entry, not the raw data. CR2 files stay in their blocks and remain recognisable because the format is TIFF-based, yet the embedded preview makes results look better than they are, so every file has to be developed before it counts. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not put the card back into the camera to inspect the folder, and do not let the body rebuild its picture index.
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 CR2 is usable when a RAW converter opens it at full sensor resolution and the picture develops without stripes or a grey lower half.
