What is this HEX string?

Question

C++ / C#

There is a file in which an image and some text string are combined. If you open the file with a hex editor, then the top file looks like this:
424D BE70 0000 0000 0000 3E00 0000
0000 0000 0000
0000 0000 80000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 FFFF FF00 FFFF
FFFF FFFF FFFF FFFF ffff ffff ffff ffff
ffff ffff ffff ffff ffff ffff ffff ffff ffff
ffff ffff ffff ffff ffff ffff ffff
ffff ffff ffff ffff ffff ffff ffff ffff
This file is then used in a C program, and it is necessary to extract this line from it somehow. I don't know the text string itself. I really hope for your help :)

It's BMP, probably. You can read more about steganography, for example.
