TrueZIP is a Java based virtual file system (VFS) 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, TrueZIP 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, TrueZIP provides the interfaces and classes to write file system drivers which plug-in to its federated file system space.
