You can delete an entire project Sketchbook, which will delete everything in that project. The project name will no longer appear in your list of “Existing Projects.”
Note: You can also delete a project outside of EQ7 using File Explorer of Finder by navigating to Documents > My EQ7 > PJ7. Select the file and send it to the Recycle Bin or Trash Can.
To delete only an item or items from a Project, see Deleting an item from the Sketchbook
To delete multiple items at a time, see Deleting multiple Sketchbook items simultaneously
Don’t worry if you see a deleted project name in the Most recently used projects list of the Project Helper. The name will be bumped off the list once other projects are opened.
