Unfortunately end rule will not work for braw files. "\x73\x6B\x69\x70" = "skip", bytes preceding it is size of skip 'sub-atom' and thus variable. You'll possibly/probably find hundreds of skip atoms throughout a file. In case I am looking at right now, it is the case.

Are NOT conditions also possible?

So, = \x00\x00\x??\x73\x6B\x69\x70 AND NOT \x00\x00\x0C\x73\x6B\x69\x70

I had to use DMDE to make this work: https://youtu.be/ocQ0gguev7c

There's a problem I've run into. The files you sent to me have different ends. 5 of them have the same end, the rest 2 files have different ends. So, my solution is the following.
1. First, scan the disk with the following description file:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<FileTypeList version="2.0">
    <FileType id="50003" group="BRAW" description="braw file type 1" features="" extension="braw">
        <Begin combine="AND">
            <Signature>\x00\x00\x00\x08\x77\x69\x64\x65</Signature>
            <Signature offset="11">\xF8\x6D\x64\x61\x74</Signature>
        </Begin>
        <End combine="OR">
            <Signature offset="8" from="end">\x00\x00\x09\x73\x6B\x69\x70\x00</Signature>
        </End>
    </FileType>
</FileTypeList>
This will find the files with this most popular end.
2. Then scan the disk with the next description file:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<FileTypeList version="2.0">
    <FileType id="50003" group="BRAW" description="braw file type 2" features="" extension="braw">
        <Begin combine="AND">
            <Signature>\x00\x00\x00\x08\x77\x69\x64\x65</Signature>
            <Signature offset="11">\xF8\x6D\x64\x61\x74</Signature>
        </Begin>
        <End combine="OR">
        </End>
    </FileType>
</FileTypeList>
This will find all braw files, including the braw file type 1 ones, but without clear file ends.
Turn off all file systems on the Scan dialog box and leave only BRAW file types enabled on the Known File Types box.
As I understand, these files are huge, chances are high that they are fragmented, so success isn't guaranteed.

There are enough samples, the problem is that the files are huge and therefore they are difficult to analyze.
