Customizations are stored in files located in various subfolders at one of three locations:
User is the location for your personal customizations. Typically, it is C:\users\(name of user)\Autodesk\Softimage_2013 on Windows or ~/Autodesk/Softimage_2013 on Linux. This is the default location for storing new customizations that you create.
Workgroup is the location for customizations that are shared among a group of users working on the same local area network. For information about setting a workgroup, see Creating and Using Workgroups.
Installation (Factory) is the location for presets and sample customizations that ship with Autodesk Softimage. It is located in the directory where the Softimage program files are installed. It is not recommended that you store your own customizations here.
When using the browser to access files on disk, you can switch among these three locations using the Paths button.
