Please be aware that the link to the dev's site above lands on a page that shows only three OS X apps, none of which are FileUtility. Going to the MAS and clicking on the FileUtility Support link lands on a blank page.
While I haven't used this software, I have used other apps from Limit Point, and I tried to contact the dev, but no answer. I'm just a bit concerned about apps that are recently updated here on MU whose support seems to be invisible.
In the case of Limit Point, I hope this is soon corrected as I do like the several apps that I own from them.
