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. -
