One of the most boring aspects of having a Web site, is to check if the site links actually work, and to remember what files have changed since last site update. This can take hours to do manually, but if you let Crystal SiteUpdater do it, you can have your Web site fully updated in seconds!. - Just tell the program where your Web site is located, and it will automatically validate all the links on the site, and update the site contents on the FTP server if you have changed it locally. - Simple as that!
