Recover data from an exFAT SDXC card
How can I recover files from an SDXC card?
Short answer
Usually well, because SDXC cards over 32 GB come formatted as exFAT, whose deleted entries often keep names, sizes and cluster locations. Confirm the file system really is exFAT, connect the card through a stable reader, scan it read-only and export to a different disk with enough free space for large video.
The situation
Large photo, video, or audio files are deleted or hidden on a card over 32 GB.
An SDXC card is any card above 32 GB, and it leaves the factory formatted as exFAT. That matters here because exFAT directory entries keep a deleted file's name, size and first cluster for a while, which is a far better starting point than raw carving.
01 / Diagnose
Work out what actually disappeared
Large cards hold large files, and that shapes the case. A single 4K clip or a burst of RAW frames occupies thousands of contiguous clusters, so a deleted entry usually points at one continuous run rather than scattered fragments. Reformatting to FAT32 for an older device, or a reader that renegotiates the bus mid-read, are the two things that commonly complicate an otherwise straightforward SDXC case.
SDXC commonly uses exFAT, allowing deleted-entry metadata and allocation state to be compared with remaining media structures.
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 in a card reader connected directly to the computer, not through a hub or a chain of adapters that can drop out.
- 2
Confirm in the disk utility that the volume really is exFAT and that the capacity shown matches the size printed on the label.
- 3
Scan read-only and prefer the results that still carry names and sizes from the directory; they are the ones with the most context.
- 4
Export to a disk with more free space than the card holds, because large video files fail silently when the destination runs out mid-write.
Do not put the card back in the camera between attempts, do not let the operating system check or repair the volume, and do not export onto the card itself. Each of those writes into the space the deleted entries still point at.
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.
This route assumes an ordinary unencrypted card that the reader enumerates at its true size. File Recovery Hero handles exFAT and FAT32, but not an encrypted card, a card the controller no longer presents correctly, or a card with physical damage.
04 / Verify
Check the recovered content, not just its name
Check the exported file sizes against what the entries promised, then open the material itself: photos at full resolution rather than as thumbnails, clips played to the last second. On a large card a partial export often looks right in a file listing and fails only in playback.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can exFAT SDXC card be recovered in this situation?+
An SDXC card is any card above 32 GB, and it leaves the factory formatted as exFAT. That matters here because exFAT directory entries keep a deleted file's name, size and first cluster for a while, which is a far better starting point than raw carving. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not put the card back in the camera between attempts, do not let the operating system check or repair the volume, and do not export onto the card itself.
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?+
Check the exported file sizes against what the entries promised, then open the material itself: photos at full resolution rather than as thumbnails, clips played to the last second.
