**Store URL format**: `file://`*path*

This store allows reading and writing a binary cache stored in *path*
in the local filesystem. If *path* does not exist, it will be created.

For example, the following builds or downloads `nixpkgs#hello` into
the local store and then copies it to the binary cache in
`/tmp/binary-cache`:

```
# nix copy --to file:///tmp/binary-cache nixpkgs#hello
```

Title: Local Filesystem Binary Cache (`file://` URL)

Summary

This document describes the `file://` URL format for a binary cache, which enables reading and writing a binary cache directly on the local filesystem. The specified path will be created if it does not already exist. An example command `nix copy --to file:///tmp/binary-cache nixpkgs#hello` demonstrates copying a package to such a local binary cache.
