libeclipse-core-filesystem-java - 1.7.200+eclipse4.10-1 main

The Eclipse Platform Resources component provides the fundamental model
underlying the IDE portion of the Eclipse Platform. This includes the
central concepts of resources (projects, folders, and files), builders,
natures, resource change listeners, etc.
.
This package contains the org.eclipse.core.filesystem bundle which provides
an abstract, generic file system API, including an implementation of this
API for the local file system. This is the API through which the resources
plugin accesses an underlying file system.
