The program belongs to System Tools.
From the developer:
Pref-Ex...You do not like nasty preferences files? Me neither. That is why I wrote this utility.
It contains a timer which scans your pref-folder (Username:Library:Preferences) and tells you when new ones are created.
You can variate the time interval but do not forget, Pref-Ex needs some performance to scan your (maybe full of trash) prefs folder.
