Oh yes I definitely agree. I think I said that in an earlier post that although the OS supports it, 3rd party utilities need to have the support added individually. In further testing I am finding out just how the files are being passed to these utilities via Explorer - as shortnames - at least that is my findings so far. That would explain why a program from 2004 is able to open these files indirectly. It also may be a way for the support to be implemented in Ztree somewhat directly without directly supporting LFNs and requiring major rewrite - I refer you to Laurent's suggestion but I would think it would be better as some option of Alt O. Anyway the discussion goes on.
