Discard and Delete Artifacts
Discarding changes you've made (no matter how many times you have saved them,), reverts the artifact back to the last published version.
To discard changes to an artifact, click the Discard button () in the artifact toolbar. You can also use the Discard All button () in the main toolbar in the Explorer to discard all changes to every artifact across your project.
To delete an artifact, click the Delete button () in the artifact toolbar.
