Provides an API to be extended by a file system implementation.

## Package Specification

This package specifies the provider API for the file system plug-in. This API is used by plug-ins that are installing file system implementations that interact with some specific backing store. These implementations are accessed by clients using the generic file system API in the `org.eclipse.core.filesystem` package. File system implementations are installed using the `filesystems` extension point.
