I know that AccessEnum is really old, however there is a display issue when it encounters a really long pathname+filename ... the security permissions simply display as a set of question marks ???
Once the pathname+filename is shortened to somewhere around 240 characters or less, the permissions display correctly.
This in turn prompts me to suggest that some other pathname+filename length checking tool might be useful. I have never understood why Microsoft's filesystem has these apparent limitations. Preferably it should stop you from placing the excessively long folder+file combination in the first place.
