    jCIFS Filesystem

    Wraps jCIFS as a java filesystem

    This library is a Java 7 filesystem for accessing CIFS/SMB resources over network. Internally it uses jCIFS and hides the library behind the java.nio.file.Path interface and its friends. Please download the newest version of jCIFS from http://jcifs.samba.org/. You can get access to a cifs/smb file simply by using Paths.get(new URI("smb://hostname/share/filename")) and manipulate the returned Path with the utility class java.​nio.​file.​Files. So you can use one API to access local and remote files with your java application. The jCIFS config can be set with the newFileSystem(URI uri, Map<String, ?> env) method of the CIFSFileSystemProvider class.
