Answer 1

In more recent sshd versions you can use org.apache.sshd.common.file.virtualfs.VirtualFileSystemFactory and supply it to the SshServer instance via method setFileSystemFactory.

Snippet:

VirtualFileSystemFactory fileSystemFactory = new VirtualFileSystemFactory();
fileSystemFactory.setDefaultHomeDir("home.directory");
sshd.setFileSystemFactory(fileSystemFactory)

Answer 2

In Default it takes the root path from System property called user.dir

Inorder to change this, you can override getVirtualUserDir() in NativeFileSystemView and return your path.

    sshd.setFileSystemFactory(new NativeFileSystemFactory() {
        @Override
        public FileSystemView createFileSystemView(final Session session) {
            return new NativeFileSystemView(session.getUsername(), false) {
                @Override
                public String getVirtualUserDir() {
                    return  "C:\\MyRoot";
                }
            };
        };
    });
