The jvvfs package implements a pseudo virtual filesystem abstraction. The package essentially constructs a unified namespace from sets of mounted archives (such as directories, zip files, etc). It is inspired by PhysicsFS but does not contain support for old proprietary/obscure archive formats.


  • Transparent mounting of archives/directories into a unified namespace.
  • Supports the zip file format (using the Java standard library implementation, for better or worse).
  • 94.4% automated unit test coverage of executable code.
  • ISC license.
  • Platform independent (tested on FreeBSD, Linux, Mac OS X, Solaris, Windows XP).
