Checking out a folder into an existing project
To check out a folder from a CVS repository into an existing project in the 
  Workbench, you can use either the Checkout wizard or Check 
  Out As from the CVS Repositories view. Follow these steps to use the 
  Checkout wizard.
  - Launch the 
    
    Checkout wizard.. 
  - Select the desired repository from the list of known repositories or, if 
    the desired repository is not in this list, choose to create a new repository 
    location and click Next. If entering a new repository location, enter 
    the repository information and click Next when completed.
 
  - Either select one or more modules from the list of existing modules or type 
    in the name of the module to be checked out and click Next.
 
  - Choose whether to check out one or more selected modules into an existing 
    project and click Next.
 
  - On the next page you can provide the following information: 
    
      - Target folder name (only when checking out a single 
        module):  The name of a local folder in which the contents of the remote 
        folder will be placed. Note: If the local folder exists, its 
        contents will be deleted and replaced by the contents of the remote folder.
 
      - Parent of target folder: The existing local folder 
        into which the target folders will be created.
 
      - Checkout sub-folders (only when checking out a single 
        module): The option to indicate whether 
        the sub-folders of the remote folder should be checked out as children 
        of the target folder.
 
    
   
  - (Optional) Select the tag to check out from and click Finish.
 
Note: Only folders within non-shared projects or projects shared with 
  the same CVS repository as the selected remote folder are valid targets for 
  the Checkout Into operation. Also, if the target project of the operation 
  is an unshared project, the project will be connected to the CVS repository 
  (i.e. the project will become a shared CVS project) but any pre-existing content 
  will be ignored.
