I downloaded the files from Google Drive. They are huge and I need some time to analyze them.

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

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.
