Manual deletion refers to the process where a user intentionally removes files, data, or records from a system or device, rather than relying on automated tools or scheduled scripts. This action is typically performed through user interfaces, command-line instructions, or direct interaction with the file system. Manual deletion is often used when specific data needs to be removed for privacy, security, or organizational reasons. However, it can be less reliable than automated processes, as it depends on user accuracy and attention. In cybersecurity, careful manual deletion is crucial to prevent accidental data loss or incomplete removal of sensitive information.
