Recover Lumix RW2 after formatting the card
Can RW2 files be recovered after a Lumix format?
Short answer
Often yes, as long as you have not taken new photos: formatting in the Lumix replaces file-system metadata before the old image data is necessarily overwritten. Every new shot on that card can destroy RW2 files for good. Remove it untouched, scan read-only for RW2 and JPEG, and save the results on another drive.
The situation
The camera formatted a card containing unbacked-up RW2 photos.
Formatting in the Lumix is a quick operation that lays a fresh file system on the card in a second or two. It does not overwrite the RW2 photographs themselves, which is why a card formatted by mistake is very often still worth scanning.
01 / Diagnose
Work out what actually disappeared
The camera writes new allocation structures and an empty DCIM, then treats the whole capacity as available. Your unbacked-up RAW frames stay in place until the next shot claims that space, and because RW2 files are large, even the first few frames after a format can destroy a considerable part of the session. Timing matters more here than technique does.
Quick formatting replaces metadata before necessarily overwriting every old image extent.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Stop using the card the moment you notice the format, and do not power the camera on again with it inserted.
- 2
Put it in a reader and check that the volume appears with its full capacity and stays mounted without dropping.
- 3
Scan the entire volume read-only for RW2 and JPEG, since the fresh directory offers no useful path to follow.
- 4
Export the findings to a drive that is not the card and inspect a handful of pictures straight away.
Do not try a second format, a card repair or a test photograph, because each writes into the free space where your pictures still are. Software offering to restore the file system is equally wrong here: the aim is reading the data area, not rebuilding the replaced structure.
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.
Every shot taken after the format reduces what remains, and an overwritten frame does not come back. File Recovery Hero reads exFAT and FAT media read-only, exporting to a different drive once a one-off 50 EUR licence is in place; it restores neither original file names nor a damaged RW2.
04 / Verify
Check the recovered content, not just its name
Judge each RW2 by opening it in your converter at full size and looking for a clean image across the whole frame. Frames from later in a session often come back more reliably, so test the early ones deliberately. File names will not match the originals, so sort the set by capture time.
Keep the source until two verified copies exist. One working preview is not enough.

Questions about this recovery case
Can formatted Lumix exFAT card be recovered in this situation?+
Formatting in the Lumix is a quick operation that lays a fresh file system on the card in a second or two. It does not overwrite the RW2 photographs themselves, which is why a card formatted by mistake is very often still worth scanning. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not try a second format, a card repair or a test photograph, because each writes into the free space where your pictures still are.
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?+
Judge each RW2 by opening it in your converter at full size and looking for a clean image across the whole frame.
