ren (or rename) is a shell command for renaming a file and in some implementations (such as AmigaDOS) a directory.
Some shells with ren also provide a move command that provides for moving between directories. On systems that do not support a move command (such as MS-DOS older than 6.00), the user could copy a file to a new destination and then delete the original file. In DOSBox, ren can move files.
