On the
  
  
  General > Workspace
  preference page, you can manage 
  various IDE-specific workspace preferences settings in the Workbench. 
| Option | Description | Default | 
| Build automatically | If this option is turned on, then the Workbench will perform an automatic build whenever a modified resource is saved. | On | 
| Refresh using native hooks or polling | If this option is turned on then the workspace resources will be synchronized 
        with their corresponding resources in the file system automatically
        using native refresh providers (on Windows) or a polling mechanism.
      	 Note: This can potentially be a lengthy operation depending on the number of resources you have in your workspace.  | 
    Off | 
| Refresh on access | If this option is turned on then files discovered to be out-of-sync by the workspace, for example while accessing the file content by an editor, will be automatically asynchronously refreshed. | Off | 
| Save automatically before build | If this option is selected, when a manual build is performed the Workbench 
      will automatically save all resources that have been modified since the 
      last build was performed. | 
    Off | 
  
| Always close unrelated projects without prompt | If this option is selected, unrelated projects will be closed without prompt.
     Uncheck this option if you want to be asked first.  | 
    Off | 
| Workspace save interval (in minutes) | This number indicates how often the state of the workspace is automatically saved to disk. | 5 | 
| Workspace title (shown in window title) | This string plus " - " will be prepended to the computed title of each workbench window. | |
| Open referenced projects when a project is opened | If this option is enabled opening a project will also open and closed projects it references. Select prompt if you wish to be asked first. | Prompt | 
| Text file encoding | Use this option to specify the encoding to use when saving text files in editors. | Default (Cp1252) | 
| New text file line delimiter | Use this option to specify the line delimiter to use for new text files.
         Note: 
        This will generally not affect the file line delimiter for  | 
    Default |
