Nikon NRW recovery from an exFAT camera card
How do I recover deleted NRW files from a Nikon camera?
Short answer
First stop using the card, then scan it read-only for NRW. This TIFF-derived RAW format from Nikon Coolpix compacts has a header that is easy to find, but it only matters if the complete sensor data behind it survived. Export to another drive and count a file as recovered once it develops fully.
The situation
NRW originals were deleted during review or import.
NRW is the RAW format of Nikon's compact cameras and is built on the TIFF structure, which makes its header easy for a scan to spot. A header on its own is worth little, though: the sensor data behind it has to be complete before the picture will develop.
01 / Diagnose
Work out what actually disappeared
Deleting an image in the camera or in a file manager releases the directory entry and marks that file's clusters as available, while the NRW body stays untouched until something else is written there. Because a TIFF-derived file opens with a small header describing where the image strips sit, a partial recovery can look convincing in a file list and still collapse when a converter reads past the header.
NRW is TIFF-derived and a plausible header must be backed by complete sensor data.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Take the card out of the Coolpix before you review anything further and leave the camera switched off.
- 2
Note how many NRW frames are missing and from which part of the session, so the recovered count can be judged later.
- 3
Read the card through a card reader and scan the volume read-only for NRW, adding JPEG if you shot both formats.
- 4
Export to a second drive and open each NRW in a converter that supports the Nikon compact model in question.
Do not take another frame on this card and skip any attempt to restore images from the camera menu. Renaming results to NEF in the hope that a converter accepts them helps nobody either: the two formats are related but not interchangeable, and the rename only masks real damage.
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.
Older converters sometimes refuse NRW from a particular model, so try current software before writing a file off. File Recovery Hero reads exFAT, NTFS and FAT16/FAT32 media read-only and exports elsewhere; it does not repair a truncated RAW file or read a card with hardware faults.
04 / Verify
Check the recovered content, not just its name
Development is the test. A sound NRW opens at full resolution, reacts to exposure and white balance adjustments and looks clean across the entire frame. Grey or striped areas along the bottom mean the file ends before the image data does, whatever its size in the file list suggests.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can Nikon exFAT NRW card be recovered in this situation?+
NRW is the RAW format of Nikon's compact cameras and is built on the TIFF structure, which makes its header easy for a scan to spot. A header on its own is worth little, though: the sensor data behind it has to be complete before the picture will develop. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not take another frame on this card and skip any attempt to restore images from the camera menu.
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?+
Development is the test.
