This tool closes the current project, without saving it, and then discards it from your working area.
All changes you have made since you last updated the project are lost. If you only wish to lose changes made since your last Save operation, use File Close instead.
NOTE: If your Database Operation mode of operation is set to Simple Interface, you do not need to use this tool. On closing a project, it is automatically updated to the central database. This tool might be greyed out, or might not be visible on your menu.
