Code42 helps you get back to work faster by backing up and restoring your Mac computer's user and application preferences. Most applications save preferences as .plist or .pref  files. These files contain customized settings for your applications such as the default homepage for your Internet browser, how often an application saves your work, or an application's default font. 

This article explains how to back up and restore user and application preferences on a Mac computer. If you have a Windows computer, you can use Code42 to migrate Windows user profiles and data


Applications store and interact with preferences differently. We recommend you review the application's documentation for its specific preference file location. You should also test backing up and downloading preference files for the applications in your environment. 

Step 1: Back up Preferences and Application Support folders

Most application and user preferences are stored under the following folders: 

  •  /Users/<username>/Library/Preferences/
  • /Users/<username>/Library/Application Support/

To make sure these folders are backed up: 

  1. Sign in to the administration console. 
  2. Go to Settings > Device Backup. 
  3. Select the Backup tab. 
    device backup settings
  4. Under File Selection, add :users to the included files. 
  5. (optional) Click push push  to apply this setting to existing users.
  6. Under Excluded files, verify that you are not excluding .plist or .pref file extensions.  
  7. (optional) Click push  push to apply this setting to existing users
Excluding other files
You may want to exclude some files under Application Support from being backed up by Code42. See exclude or include files using file type and regular expressions for more information. 

Step 2: Test back up and restore

We recommend that you use a test device to test the back up and restore of each user and application preferences because applications may vary in the steps needed to successfully migrate preferences. Review the application's documentation for specific preference file locations.

Restore your user and application preferences

  1. Download and install the CrashPlan app on the user's device. 
  2. Download the backed up preference settings. You can do this a couple different ways:
