Which of the following is NOT a type of file in computing?

The correct answer points out that a cryptographic file is not recognized as a standard type of file in computing. While there are file types that concern encryption and decryption processes—essentially involving cryptography—they don’t correspond to a distinct classification like executable, data, or text files do.

Executable files are designed to perform actions when executed, typically containing machine code. Data files store information and can be in various formats, encompassing anything from databases to images. Text files are used to contain plain text, often editable, and are readable by both humans and machines.

In contrast, the term "cryptographic file" is too broad and doesn't represent a standard file type, as cryptographic operations can be applied to many existing file types for securing data. This distinguishes it from other established types of files that serve clear, defined purposes in a computing context.
