DynamicExplorer allows you to move seamlessly from one-dimensional folders to multidimensional categories. Use the integrated Windows Explorer functions (which are free) to continue to manage your files in your accustomed fashion, while getting used to the benefits of multiple categorization. Easily assign a file to multiple categories, yet save it to disk only once. Double Windows Explorer panes (also free) make comparing folders and copying files secure and easy. Tight integration of folders and categories allows you to keep control of your files, even while working in the logical world of categories. Feel at home in the familiar three-window design. Administer all your documents, e-mails, favorites, pictures, and MP3s from one point. There is no need for parallel searching in Internet Explorer or Outlook or on the hard disk. The built-in preview and a series of assistants help make the administration of files easy.
