This module provides convenient access to the (virtual federated) file system space for TrueVFS client applications. It features simple, uniform, transparent, thread-safe, read/write access to archive files as if they were virtual directories in a file system path. This module also provides Swing GUI classes for viewing file trees and choosing entries in archive files.

There is a newer version: 0.14.0
