What is the difference between text files and binary files?
A text file is something that you and me can read just by opening it with some text editor, a binary file is something meant for computers. It's written in something that's understandable by machines, and that's 'zeroes' and 'ones'.

A binary file always needs a matching software to read or write it.
The text looks readable to a human or at least moderately sane. Even if it contains a heavy proportion of punctuation symbols (like HTML, RTF, and other markup formats), there is some visible structure and it’s not seemingly random garbage.
-Binary Files
Binary files typically contain a sequence of bytes, or ordered groupings of eight bits. When creating a custom file format for a program, a developer arranges these bytes into a format that stores the necessary information for the application. Binary file formats may include multiple types of data in the same file, such as image, video, and audio data. This data can be interpreted by supporting programs, but will show up as garbled text in a text editor. Below is an example of a .PNG image file opened in an image viewer and a text editor.
-Text Files
Text files are more restrictive than binary files since they can only contain textual data. However, unlike binary files, they are less likely to become corrupted. While a small error in a binary file may make it unreadable, a small error in a text file may simply show up once the file has been opened. This is one of reasons Microsoft switched to a compressed text-based XML format for the Office 2007 file types.

As you can see, the image viewer recognizes the binary data and displays the picture. When the image is opened in a text editor, the binary data is converted to unrecognizable text. However, you may notice that some of the text is readable. This is because the PNG format includes small sections for storing textual data. The text editor, while not designed to read this file format, still displays this text when the file is opened. Many other binary file types include sections of readable text as well. Therefore, it may be possible to find out some information about an unknown binary file type by opening it in a text editor.
Binary files often contain headers, which are bytes of data at the beginning of a file that identifies the file's contents. Headers often include the file type and other descriptive information. For example, in the image above, the "PNG" text indicates the file is a PNG image. If a file has invalid header information, software programs may not open the file or they may report that the file is corrupted.

Text files may be saved in either a plain text (.TXT) format and rich text (.RTF) format. A typical plain text file contains several lines of text that are each followed by an End-of-Line (EOL) character. An End-of-File (EOF) marker is placed after the final character, which signals the end of the file. Rich text files use a similar file structure, but may also include text styles, such as bold and italics, as well as page formatting information. Both plain text and rich text files include a (character encoding| characterencoding) scheme that determines how the characters are interpreted and what characters can be displayed.
Since text files use a simple, standard format, many programs are capable of reading and editing text files. Common text editors include Microsoft Notepad and WordPad, which are bundled with Windows, and Apple TextEdit, which is included with Mac OS X.
