You can delete a Version Cue project in Bridge or any Version Cue-enabled Adobe Creative Suite component, or by using Version Cue Server Administration. You can’t delete a project if any user has files that are marked as Checked Out or In Use (Acrobat).
Deleting a project permanently erases all of its files (including versions) and folders from the Version Cue Server, and erases shortcuts to the project and the local project files on your computer. (The local project files created on other users’ computers are not deleted until they disconnect from the deleted project.)
