amparida:

I think you mean you have a binary file, rather than a hex file.

If you want to get meaningful information from the file, you need to know what *type* of binary file it is--unless you'd be satisfied by just changing the binary bytes into their hex representation. Then you'd be able to open the file, but it would still be gibberish.

If you're on a *nix box, you should have a "file" command which will look at the file and try to identify the file type for you.
