The File

The idea
A file is a collection of related information stored on a storage instrument — the smallest storage unit from the user's perspective, named in two parts: a name and an extension.
In practice
An essay saved once becomes one named, findable, durable thing.
Where people slip
Below the user's smallest unit sit layers the OS keeps private.
