sealed trait Files[F[_]] extends FilesPlatform[F]
Provides operations related to working with files in the effect F
.
An instance is available for any effect F
which has an Async[F]
instance.
The operations on this trait are implemented for both the JVM and Node.js.
Some operations only work on POSIX file systems, though such methods generally
have "Posix" in their names (e.g. getPosixPermissions
). A small number of methods
are only available on the JVM (e.g. variant of list
which takes a glob pattern) and
are indicated as such in their ScalaDoc.

Returns an infinite stream of data from the file at the specified path. Starts reading from the specified offset and upon reaching the end of the file, polls every
