Can you upload the original binary data please?. It's a bit difficult to do any analysis otherwise.

So are they original data files or not?. You say they are raw datablocks, does that mean the header is removed. Can you start from the beginning - what is the origin of the files and how are they used?. Are the fixed size or variable?

So are you working on this, Git? (or anyone else?) I will love you forever if you are ;)

I thought you had solved it. It's a jigsaw puzzle now and you will have to do that puzzle before you can find out where each piece's coordinattes are kept. Firt thing you need is a utility to show the picture and some of the header at the same time.

Do you know of a utility that can do that?

Any gfx program like paintshop pro etc will show a raw file, or you can create and paste a bmp heder onto the raw data. If you can isolate the image data (sounded like you had achieved that). By raw, I mean uncomporessed pixel data in an X-Y array. TIFF, BMP, and many others can be used to store raw image data. As PNG is in the poublic domain it may be the easiest to get source code for and will display in almost anything, even a browser, although png is really meant for compressed data.

Actually, I just re-read the thread and noticed your "this was created" link. It sounds like you have already done what I am suggesting. Are you absolutely sure it is not audio?... What program created the file?. WHoever wrote that program knows exactly what the file format is - are you sure they won't share that info with you?

What makes you think it might be audio, by the way?

One of the file analysers thought many of the file parts had a 96% chance of being HSC audio files.

Interesting. Which analyzer was that?
