You can import and export preferences. Preferences are saved as files with a .xsipref extension. They are text files and can be edited manually in any text editor.
You can export your preferences if you want to use them on another installation of Softimage or share them with other users.
In the left pane of the Preferences window, right-click on the node you want to export.
For example, right-click on the Scene Colors node to export that category, or right-click on the Preferences folder to export all your preferences.
In the file browser that opens, specify a path and file name for the exported preference file, and click OK.
