Deleting Folders

To delete a folder with the Documents and Media API, you must use one of the two deleteFolder methods discussed in Deleting Entities. The steps here show you how. For general information on using the API, see Documents and Media API.

Follow these steps to delete a folder:

  1. Get a reference to DLAppService:

    private DLAppService _dlAppService;
  2. Get the data needed to populate the arguments of the deleteFolder method you wish to use. Since it’s common to delete a folder specified by the end user, you can extract the data you need from the request. This example does so via javax.portlet.ActionRequest and ParamUtil, but you can get the data any way you wish. Also note that this example gets only the folder ID because the next step deletes the folder with deleteFolder(folderId):

    long folderId = ParamUtil.getLong(actionRequest, "folderId");

    If you want to use the other deleteFolder method, you can also get the repository ID, parent folder ID, and folder name from the request.

  3. Call the service reference’s deleteFolder method you wish to use with the data from the previous step. This example calls deleteFolder with the folder’s ID:


You can find the full code for this example in the deleteFolders method of Liferay DXP’s EditFolderMVCActionCommand class. This class uses the Documents and Media API to implement almost all the Folder actions that the Documents and Media app supports. Also note that this deleteFolders method, as well as the rest of EditFolderMVCActionCommand, contains additional logic to suit the specific needs of the Documents and Media app.
