VFS - Virtual File System

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

Its homepage is located at: https://commons.apache.org/proper/commons-vfs/.
