Bill,

If you call the file copy primitive, it will try to load the plugin.
The #listLoadedModules method will show you the loaded plugins, hence:

  FileList new primitiveCopyFileNamed: 'foo' to: 'bar'.
  SmalltalkImage current listLoadedModules
      detect: [:plugin | 'FileCopyPlugin*' match: plugin]
      ifNone: ['the FileCopyPlugin is not installed']
