We are just upgrading to 6.5.2, with latest PSOToolkit as well. In one of our previous discussions, you mentioned there is a new getParentFolderPath() method. This new method takes $sys.assemblyItem as a parameter and computes the parent path for the current folder. (All this will help me deal with paste-as-link issues.)
However, my version of tookit still has only the original method (itemguid as param). There’s nothing else in psoFolderTools class?
