Sorry my mistake.
I thought that you were indicating that the .RAR file was what you were asking about.
Instead, on reading more closely, I find that you intentionally compressed the sample file for someone to examine.
Anyway, the un-compressed file has no file extension so that does not help us.
And the data inside the un-compressed file is not in a readily recognizable form.
With these types of questions, the first question we have to ask is WHO OWNS THE DATA?
There can be legal issues about 'harvesting' someone else's data for your use.
