Rename (computing)

In computing, "rename" refers to the operation of changing the name of a file, directory (folder), or other object within a file system or software system. This operation does not typically modify the contents of the object itself; instead, it only alters the identifier used to access the object.

The rename operation is a fundamental function provided by most operating systems and file managers. It allows users and programs to organize and manage files and directories more effectively. Renaming can be performed through a graphical user interface (GUI), command-line interface (CLI), or programmatically via system calls or library functions.

The specific behavior of the rename operation can vary slightly depending on the operating system or file system in use. For example, some systems may support atomic renaming, where the rename operation is guaranteed to be completed in its entirety or not at all, even in the event of a system failure. Others may impose restrictions on the length or characters allowed in a new filename.

The rename operation is distinct from copying and deleting. Copying creates a duplicate of the object with a new name, while deleting removes the object from the file system. Renaming simply changes the object's identifier.

In database systems, the term "rename" can also refer to the act of changing the name of a table, column, or other database object. Similar to file system renaming, this operation generally only affects the object's identifier within the database schema and does not alter the underlying data.

Beyond file systems and databases, the concept of "rename" can extend to various programming contexts. For example, in software development, refactoring code might involve renaming variables, functions, or classes to improve readability or maintainability. The core principle remains the same: to change the identifier of an object without altering its essential nature.
