# Method System.clonefile()

Method clonefile

  ``void` clonefile(`string` `from`, `string` `to`)`

Description

  Copy a file `from` with copy-on-write semantics to the destination named `to`.

Note

  This function is currently only available on macOS and Linux, and then only when `from` and `to` reference a common file system with copy-on-write support (e.g. an APFS volume).
