filecopying

File copying is a fundamental operation in computing that involves creating an exact duplicate of a file in a different location. This process is essential for various tasks such as backing up data, transferring files between devices or storage media, and creating working copies of files for editing or experimentation. When a file is copied, the operating system reads the data from the source file and writes it to a new file at the specified destination. This new file will have the same name, content, and often the same metadata (like creation date and permissions) as the original, depending on the copying method and operating system.

There are numerous ways to perform file copying. Command-line interfaces in operating systems like Windows, macOS, and Linux offer commands such as `copy` or `cp` for this purpose. Graphical user interfaces provide drag-and-drop functionality or copy-paste options within file explorers. Specialized software, including backup utilities and file synchronization tools, also leverage file copying mechanisms, often with advanced features like incremental backups or conflict resolution. The efficiency and reliability of file copying are critical for data integrity and system performance.
