TrueVFS
· TrueVFS is a virtual file system (VFS) for Java 7 which enables client
applications to perform CRUD (Create, Read, Update, Delete) operations on
archive files as if they were virtual directories, even with nested archive
files in multithreaded environments.
As a library, TrueVFS provides simple, uniform, transparent,
thread-safe, read/write access to archive files as if they were
virtual directories in a file system path.
As a framework, TrueVFS provides the API to write file system drivers which
plug-in to its federated file system space.
