Since the expiration time is zero (the third argument, the first false) the cookie is a session cookie, which will expire when the current session ends. (See the setcookie reference).
inside Cookies file. (which is an SQLite database file)
So it's not a file stored on hard drive but a row in an SQLite database file which can be read by a third party program such as: SQLite Database Browser

Chrome doesn't store each cookies in separate text file. It stores all of the cookies together in a single file in the profile folder. That file is not readable.
You can find a solution on SuperUser :
Chrome cookies folder in Windows 7:-
C:\Users\your_username\AppData\Local\Google\Chrome\User Data\Default\
You'll need a program like SQLite Database Browser to read it.
For Mac OS X, the file is located at :-
~/Library/Application Support/Google/Chrome/Default/Cookies
