Backing up Viscosity's Settings

To backup Viscosity's preferences/settings and connection data a copy should be made of the following files/folders. You can also transfer Viscosity to another computer by copying these files/folders across to the same locations on the new computer.

If you are migrating from a Mac computer to a Windows computer, we recommend you import connections into Viscosity instead of copying connections and settings to and from these locations as there are Operating System specific options that are corrected and accounted for when importing connections.


  • The Viscosity application, usually located at
  • Viscosity's Preferences file, located at:
    Your Home Folder/Library/Preferences/com.viscosityvpn.Viscosity.plist
  • Viscosity's connection data, located at:
    Your Home Folder/Library/Application Support/Viscosity

macOS contains two Library folders: a global one on your system drive and one in your Home folder. When accessing the above paths please make sure you are going through the Library folder in your Home folder, rather than the global Library folder.

The Library folder is hidden under modern versions of macOS. To get to it you'll need to open the "Go" menu in the Finder while holding down the Option key on your keyboard and click the Library item. Your Library folder will open.


  • Viscosity's Settings file, located at:
    C:\Users\<Your Username>\AppData\Roaming\Viscosity\Settings.xml
  • Viscosity's connection data, located at:
    C:\Users\<Your Username>\AppData\Roaming\Viscosity\OpenVPN

On most Windows PCs, your Application Data is hidden. For an easy way to navigate here, go to Start and search for %appdata% then press Enter. Then you can navigate to the Viscosity folder in the explorer window that opens.
