Epiware combines powerful document management software with a simple, intuitive interface built using the popular PHP language. The Epiware Document Management Suite gives users such advanced features as a smooth AJAX-enabled drag-and-drop interface for accessing files, file version and distribution control, and project management tools.
With features like individual projects and user classifications, company employees as well as trusted third-party personnel can use the same system to send and receive files while maintaining access control.
