# `Apero.File.IO`
[🔗](https://github.com/Lorenzo-SF/apero/blob/3.0.0/lib/apero/file/io.ex#L1)

I/O operations: atomic writes, checksums, temporary resources, file locking.

These functions are exposed via `Apero.File.*` delegates. You normally call them
through `Apero.File` rather than directly.

> Only pure I/O operations remain in Apero v3.0.0.
> Shell-based I/O (`Trebejo.File.IO.disk_usage/1`) moved to `Trebejo.File.IO`.
