Invisible Prefs 0.4.7
When you run Invisible Prefs, it finds and shows preferences that you didn't know were on your computer.
They may even be for programs you no longer use.
Invisible Prefs also gives you the option of deleting those preferences and saving them to a folder. Finding and deleting preferences is the extent of Invisible Prefs' functionality at this time, but it's always helpful to be able to get rid of unwanted information lurking on your computer.
For more detailed information, including on updates, please read the documentation or visit the home page.
This program can be used with Mac OS 9.0 and later, and on Mac OS X. It may work on Mac OS 8.6, but I haven't tried it on that version, and the author doesn't say.
