Package wrfs implements several extension interfaces for the io/fs package that make it possible to create and modify files. Each extension interface has one or more helper functions that make use of it. The helper functions accept any FS implementation, but return ErrUnsupported if the FS cannot support the requested operation.

wrfs re-exports the types and functions found in the io/fs package and can thus be used as a drop-in replacement for the io/fs package.
