We can usually tell if a file is binary or text based on its file extension. This is because by convention the extension reflects the file format, and it is ultimately the file format that dictates whether the file data is binary or text.
Binary files are not human-readable because the bytes they contain translate to characters and symbols that have many other non-printable characters. The text editor shows any binary file as characters such as Ø and ð. Binary files must be read by programs to be useable.
The BinaryReader class is used to read binary data from a file. A BinaryReader object is created by passing a FileStream object to its constructor.
Use utility file, sample usage:
$ file /bin/bash /bin/bash: Mach-O universal binary with 2 architectures /bin/bash (for architecture x86_64): Mach-O 64-bit executable x86_64 /bin/bash (for architecture i386): Mach-O executable i386 $ file /etc/passwd /etc/passwd: ASCII English text $ file code.c code.c: ASCII c program text file manual page
