Bug 161026 [Wizards] ProjectContentsLocationArea uses wrong file separator
org.eclipse.ui.internal.ide.dialogs.ProjectContentsLocationArea uses Linux style '/' file-separators regardless of platform. I will attach a patch against head that uses .toOSString() instead of the current .toString()
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/ide/dialogs/ProjectContentsLocationArea.java
defaultURI = existingProject.getLocationURI();
		}
		
		if (defaultURI == null || defaultURI.getScheme().equals(FILE_SCHEME)) {
			return Platform.getLocation().append(projectName).toString();
		}
		return defaultURI.toString();
	}
