File synchronization
It is no longer allowed to do any changes to files on disk. If you have done changes or experienced issues with the installation point, you can press this button to sync all files from the database to disk. This does not affect files such as the profile.xml or settings, but only the installation download page, the installation point, and the installed features and features folders. It is always safe to press this button but it is recommend that you do so during a service window to avoid concurrent file access.
