Description: ReadOnlyFile is a file that cannot be modified after it is created. This type of file is commonly used to protect data integrity, ensuring that the information contained within it remains unchanged. In the context of programming, a read-only file can be created and managed using various classes and methods from programming libraries specific to the language in use. The main characteristics of a read-only file include its ability to be read by applications and users, but not to be edited or deleted. This is particularly useful in situations where data preservation is critical, such as in configuration files, audit logs, or legal documents. Additionally, read-only files can be used to prevent accidental or malicious modifications, providing an extra layer of security. In many programming environments, a file can be set as read-only using file system properties, allowing developers to effectively control access to files. Implementing read-only files is a common practice in software development, where data protection is a priority.
