I am by now means an expert, but the questions does not make any sense.

You would need to define what an "ascii file" is, and how it is different from
a "binary file".

I guess that you could read thru the data and make sure that all bytes are in
a specific subset, perhaps a-zA-Z0-9, various punctuation, NL/CR, etc. but
even if so it does not mean that none of that data is float or int.

:>I know both of them are stream of bytes but interpreted by different ways.
:>My questions are:
:>1. How can I know this without opening it?

Not a clue.

:>2. how can I see all the information in a file, include all the control 
characters, like linein, print character and line feed, etc.

fopen in binary.

:>3. Is there any tool on Linux can open binary file?

I am sure that many can.

:>4. Is there any tool on Linux can transfer ASCII to binary and binary to 
ASCII?

What does that mean?

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
