Examples of IFileSystem

org.eclipse.core.filesystem.IFileSystem
This is the main interface to a single file system. Each file system instance manages interaction with all files in the backing store represented by a particular URI scheme.
File systems are registered using the "filesystems" extension point.

This interface is not intended to be implemented by clients. File system implementations must subclass {@link FileSystem} rather than implementingthis interface directly.
