How to delete obsolete workspace in RAD?

How can I delete workspace in Rational Application Developer (RAD). I know deleting t开发者_如何转开发he folder will delete the workspace, but it still shows me in switch workspace option in RAD.

I found that edit the org.eclipse.ui.ide.prefs will do it, but what is it that I should edit??

Thanks in advance.

THe org.eclipse.ui.ide.prefs only allows you to show RECENT_WORKSPACES for when you start Eclipse, it doesn't allow for deleting for the workspace.

To delete workspace, just delete the workspace directory (and remove it from RECENT_WORKSPACES). An explanation can be found on EclipseZone.

Update the org.eclipse.ui.ide.prefs can be found under ECLIPSE_HOME/configuration/.settings/ directory.
