I don't really even know where to start on this...

A new SoPW. And a much clearer description of

  1. The contents of the file and its formatting.

    With preferably an example of the data that contains typical contents and at least 3 records that match. If that means it would be too big to post here, then making an example available off-site shouldn't be too hard.

  2. What you are actually searching for.

    Ie. less "(Say, all blocks of character 0x20 that are at least 12 bytes long)" & "say, they shouldn't overlap between groups of 1000 byte" & "(say, the ASCII characters "U S E D" followed by the block length)".

  3. And what you want to do once you've found them.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
