This is FilesystemDataProvider and FtpDataProvider for 24, 23, 14 and 8. Add-on includes also FileSelect and FtpSelect single select components to browse filesystem and select a file. With this data provider it is easy to load local filesystem hierarchy or ftp (from server) to customized TreeGrid. The add-on includes also rudimentary icon mapper for MIME types using VaadinIcons.

The FilesystemDataProvider and FtpDataProvider can be used both in recursive (read file system data at once) and non-recursive mode (read file system data as per needed), see demo application for details.

The add-on has also FileSelect and FtpSelect field components included for simple single select file browsing.

Sample code

    	// Demo 1: Use FilesystemData non-recursively
    	
    	// When using non-recursive mode, it is possible to browse entire file system
    	// DataProvider pre-fetches root directory and rest is loaded progressively
    	// lazily
    	File rootFile = new File("C:/");
    	FilesystemData root = new FilesystemData(rootFile, false);
    	FilesystemDataProvider fileSystem = new FilesystemDataProvider(root);     	
        final Tree<File> tree = new Tree<>();
        tree.setDataProvider(fileSystem);

        tree.setItemIconGenerator(file -> {
        	return FileTypeResolver.getIcon(file);
        });
        
      
                    
        final Panel layout1 = new Panel();
        layout1.setSizeFull();        
        layout1.setContent(tree);
