RORO01  What we really need is an application which detect preference files which are not associated with any application, i.e files of applications where we have deleted the applications but forgot to delete their preference files.  
(Version 1.1.8)

FRANçOIS PELLERIN  Grat product! Thanks.

The developper could write a ReadMeFirst file to tell the dummies like myself exactly what to do with the files included in the upgrade...  
(Version 1.1.8)

DOC RENAUD  And you think you could live without stuffit expander installed ? Good luck :-)  
(Version 1.1.7)

SIDETRACKED  Works just fine for me in Tiger.

A very simple, straightforward way to check for problems in preference files. Already was able to head off a couple of problems before they became real problems. I sent a donation.  
(Version 1.1.6)

ANONYMOUS  Nice utility, but the developer should allow download of the application in .zip or .dmg archive instead of .sit, so that Tiger users aren't forced to download Stuffit.  
(Version 1.1.4)

ANONYMOUS  PT doesn't work with OS X 10.4 Tiger. Authentication to check System prefs is broken.

A workaround is to run the program as root either in the terminal or get the freeware program Pseudo. Just drop PT onto the Pseudo window and it runs as root, problem solved.  
(Version 1.1.3)

SEAN  Great!!Thank you so much John!  
(Version 1.1.1)

JOE WEAVER  Jonathan is a great developer and a good man. I released a program similar to his (I didn't know his existed), he downloaded it, and e-mailed me with some suggestions to improve it! I couldn't believe it, the "competition" is helping me! Truly a good man.

I'm in the Navy and and programming is totally new to me. I have only been scripting and programming for 4 days so he is helping me along. I can't believe it!

Thanks again Jonathan.  
(Version 1.0.2.1)

MZA INC.  I click to open app. Window appears asking for a donation. Click to later or donate. Nothing happens. App disappears. Does anyone know what gives? Have downloaded app 3 times from here and Johnathan's website with same result. Is there a preference file that I need to trash?  
(Version 1.0.1)

JAMES  Note to the developer: this is a great app, that does what it says well, runs smoothly, and is obviously a great price! Thanks for developing something like this for those of us (and others I suppose), who know a little, but not enough to do some digging inside to find any potential problems. Again, my thanks to the developer!  
(Version 1.0.1)

ROB MORTON  Have you ever noticed how great support is from I am assuming relatively small developers. I basically do not have a standard setup. I run as a regular user, but I am in the sudoers file. All this means is that I can run AppleScript Studio products that require me to be there, but I have to authenticate for just about everything. The author and I emailed back and forth for about a half a day before he enhanced the product so that I could use it without being an administrator. All of this while getting paid the huge $0 for his time. Does what it says, and seems to work great and has great support. Is there a downside somewhere, because I can not see it.  
(Version 1.0)

JON NATHAN  To my supporters, thank you. Sincerely,

To E5o: How do you give something that is free such a low value rating? For the record, this app does a lot more than just running that little bit of code. It parses the results, doesn't bother with valid files, and allows you do something constructive with the flagged files (trash them, view them, etc.)--and the code it does run is more robust in the first place,

I'm tired of being bashed for making something for free. If you don't want to use it, fine, but why bash it when, for many people, it so obviously has value?

I'm also tired of being bashed for releasing new versions of this software so quickly. If you don't want to upgrade, then don't. This is an incredibly popular piece of software with tens of thousands of downloads (not just from this site) and I feel an obligation to get it right. I really don't see the problem with that.

To the bashers, thanks for proving the adage, "no good deed goes unpunished."

(Version 1.6.9)

A FAN  I'd like to add my voice of thanks to developers who make our lives easier when dealing with technical issues. I don't have the time or guts to deal with command line entry, so the previous comments to me are petty and misguided. Less "ha ha i can enter this in the terminal why can't you", arrogance and more helpfulness as displayed by this developer (free of charge) make this a better world. Why don't you find something positive to contribute to humanity instead of making shallow negative comments.  
(Version 1.6.9)

E5O  Yeah, or you could just pop open your Terminal and type

[code]

plutil -lint Library/Preferences/*.plist

[/code]  
(Version 1.6.9)

LEO OF BORG  To the previous anon poster: shaddup. Finally we get an author who has TIME to release and fix bugs and someone like you has to complain. Engineers with clue are hard to come by, don't scare this one off!

To the author: Keep up the GREAT work, and keep the features coming. Between this and the (newly released) Panth Cache Cleaner, the (pref) deadwood is GONE. Thanks for making this program.  
(Version 1.6.9)

ANONYMOUS  A release every day sofar..man are we your guinea pigs..how bout releasing this software once its actually ready.....  
(Version 1.6.7)

HORATIO  the reminder blocks the application on quit. Nevertheless a smart little app ;-)  
(Version 1.6.5)

DAGAZ  Excellent little App., something I have been looking for a long time. Have just downloaded it and on its first run it picked up a corrupt preference. I then tried to open this preference in both TextEdit and PropertyListEditor, which confirms that it was corrupted.

Although it is really donationware rather then freeware.  
(Version 1.4.2)

THEL  'Zooks, that was *FAST*! Closing the Check Preference Files window properly quits the application now in version 1.4.2.

WTG, Jon!! ::::applause::::  
(Version 1.4.2)

THEL  The app works fine here (on a 1 GHz G4 w/Panther 10.3.2), but when you're done, don't simply close the window to quit it - select Quit Check Preference Files from the app's menu, or hit command+q.  
(Version 1.3.1)

ANONYMOUS  Check Preference Files 1.3.1 runs fine on both my Panther 3.2 machines (one is a G5), but it generates on finishing an Applescript error, Stack overflow (-2706) that comes up twice.

Have no clues.
