With Regards To Jpegdigger..

I changed it around a bit, so this is no longer accurate: https://www.majorgeeks.com/files/details/jpegdigger.html

At some point JpegDigger RAW > JPEG functionality was moved to JPEG-Repair and then there was no more JpegDigger. Few months forward: I needed a no thrills JPEG carver and since then I have added functionality. Thought it needed a name and I decided to recycle the name JpegDigger. Confusing eh? So from now on JpegDigger is a JPEG carver. Nothing really fancy and it's current shape and form are to fit my own needs.

The carver scans for JPEG magic numbers and TIFF based RAW photos.

If it detects JPEG:

- Rest of the file is parsed, following chain of JPEG markers so It can get some idea if we have a complete file + some level of error detection and correction (to at least a degree where it can be opened using a photo viewer/editor. I also have a few memory cards I tested against where it was able to defrag a few files following some simple rules of thumb.

- If TIFF based file:

It tries to grab the high res JPEG from that. Has been useful to me few times where the RAWs recovered (by ReclaiMe, R-Studio, PhotoRec etc. etc.) were corrupt and the high res JPEG was the next best thing. With many RAW types you should be able to get a full resolution JPEG.
