- etherpad.mit.edu/p/r.19b7b3e2c5ea08a61cb0bef0aeb213fd image list (February 8, 2017) We tried going over it, but it is just too much work, the huge majority of the results are just AtomSea & EMBII so not that interesting.

Does the same as this page, just that it is an uncomprehensible mess of broken links. But they have soe good ideas!
Their main techniques seem to be:
```
mkdir binout
for file in blk*dat; do echo "$file"; binwalk --dd='.*' "$file" -C binout/. --log=binout/"$file""res.txt"; done
```
and:
```
mkdir subfileout
for file in blk*dat; do mkdir subfileout/"$file"; done
for file in blk*dat; do echo "$file"; hachoir-subfile --category=image,video,audio,container,archive,misc "$file" subfileout/"$file" > subfileout/"$file""subfile.txt"; done
```
which seem promising.
These are installable on Ubuntu 23.10 with:
```
sudo apt install binwalk hachoir
```
