What is a do file and how do I open a do file?
DO are Java Servlet files associated with the web-based Java program run by a server that supports Java, such as Tomcat or IBM WebSphere. They are mapped to the Struts controller, which processes the file, and used to generate dynamic Web pages. Some webinar programs may generate DO files that are formatted as VCS files. Changing the file extension to VCS may allow these files to be imported into various scheduling programs.
