You can add an LLB to a LabVIEW project as a folder or as a file. If you add an LLB as a folder, LabVIEW uses the filename of the LLB to name the folder and adds the VIs in the LLB as items within the new folder. Right-click a target or a folder under the target, select Add»Folder (Snapshot) from the shortcut menu, and use the file dialog box to navigate to the LLB you want to add.

Adding or removing items from the virtual folder in the Project Explorer window does not affect the .llb file on disk. Use the LLB Manager window to edit an LLB on disk. You also can add the LLB to the project as an auto-populated folder to edit the LLB on disk. Right-click a target or a folder under the target and select Add»Folder (Auto-populating) from the shortcut menu.

You also can add an LLB to a project as a file. If you add an LLB as a file, the VIs in the LLB do not appear in the Project Explorer window. Right-click the target or a folder under the target and select Add»File from the shortcut menu. Use the file dialog box to navigate to the LLB you want to add. In the LLB browser, select the open folder icon labeled VI with a single period. Click the Select button to select the folder and close the LLB browser.

You also can use the Add Item method to add an LLB to a project as a folder or as a file programmatically.
