Commons VFS provides a single API for accessing various file systems.
It presents a uniform view of the files from various sources, such as
the files on local disk, on an HTTP server, or inside a Zip archive.

Some of the features of Commons VFS are:
* A single consistent API for accessing files of different types.
* Support for numerous file system types.
* Caching of file information. Caches information in-JVM, and
optionally can cache remote file information on the local file
system (replicator).
* Event delivery.
* Support for logical file systems made up of files from various file
systems.
* Utilities for integrating Commons VFS into applications, such as a
VFS-aware ClassLoader and URLStreamHandlerFactory.
* A set of VFS-enabled Ant tasks.
