Zero-byte files may arise in cases where a program creates a file but aborts or is interrupted prematurely while writing to it. Because writes are cached in memory and only flushed to disk at a later time ( page cache ), a program that does not flush its writes to disk or terminate normally may result in a zero-byte file.

Files that contain machine-executable code and non-textual data typically contain all 256 possible eight-bit byte values. Many computer programs came to rely on this distinction between seven-bit text and eight-bit binary data, and would not function properly if non-ASCII characters appeared in data that was expected to include only ASCII text.
In UTF-16, a BOM (U+FEFF) may be placed as the first bytes of a file or character stream to indicate the endianness (byte order) of all the 16-bit code units of the file or stream. If an attempt is made to read this stream with the wrong endianness, the bytes will be swapped, thus delivering the character U+FFFE , which is defined by Unicode as ...
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
A binary file is a computer file that is not a text file. [1] The term "binary file" is often used as a term meaning "non-text file". [ 2 ] Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text , such as older Microsoft Word document files, contain the text of ...
In most hex editor applications, the data of the computer file is represented as hexadecimal values grouped in 4 groups of 4 bytes (or two groups of 8 bytes), followed by one group of 16 printable ASCII characters which correspond to each pair of hex values (each byte). Non-printable ASCII characters (e.g., Bell) and characters that would take ...
-i, do not classify the file further than to identify it as either: nonexistent, a block special file, a character special file, a directory, a FIFO, a socket, a symbolic link, or a regular file. Linux [ 6 ] and BSD [ 7 ] systems behave differently with this option and instead output an Internet media type (" MIME type") identifying the ...
