After module installetion this created three folders in DesktopModules folder

• NewsAndAnnouncementImage
• NewsAndAnnouncements
• NewsAndAnnouncementTemplate

Now i want to put 3 files (file1.xml,file2.xml,file3.xml) in NewsAndAnnouncement  folder  at the installetion time not want to put manually

Please tell me what code should i add to Manifest file (.dnn) for adding additional files as mentioned above??????

But in which folder these files will be added,Because no folder mentioned here???????
