Notice

  • CyberArticle3.x/4.x books support encrypting folders while CyberArticle5.x does not.  Therefore, in case that a folder in old verion has been set a password, the articles under the folder after conversion will be encrypted (including the articles in sub-folders).  The corresponding password is as same as the original one.
