Synchronizing folders can make the installer creation process faster and easier by automatically detecting and syncing to Advanced Installer changes made to the installer files on your disk.
When you add a file to the synchronized Source folder, Advanced Installer knows to what feature and component it belongs or if it needs to ignore the file because your Filters do not accept its format. This way you will always be sure that when you add something to your project, it will be placed correctly.
