The Sync Settings feature provides you with the freedom to work from anywhere with confidence that your environment is always just the way you like it.
Sync settings for your Creative Cloud apps
For more information and detailed instructions for getting started with your favorite Adobe product, see the following:
Clear application settings
Clearing settings on the Creative Cloud does not affect the settings on your computers, but only removes the settings from the cloud.
Import previous settings and preferences
While updating to new versions of Creative Cloud apps, by default, all previously installed versions of the apps are removed. Customized preferences and settings are migrated to the latest version of the app.
You can choose to retain previously installed versions of apps or not migrate settings. See Advanced update options.
