The operation of SyncSettings is very simple. The first step made the app is to search on your disk the preferences files of your selected items. For that, SyncSettings uses a unique database maintained manually by our team. Once the location of the files found, it will either replace the local settings with the ones contained in the backup file or save the local settings in the backup file by overwriting the old ones. The last step is to update the computer caches related to preferences. It should be noted that a restart is always recommended (whereas it is not required).
