BRUCE_Y  Good idea for an info application.

But $20 for a one-trick product that only gets updated once every 15 to 18 months is Too Much $.

In my opinion.

Please, Lower the price. You will find many more buyers.

(Last app update was 6-2006, before that 3-2005.)

DOM21  Works as advertised. Not sure about $20 though. YMMV.

Version1.2.1

Get the TRUTH about your Mac OS X files.

Requires Mac OS X 10.2 or higher (10.3.5 or later recommended).

List Price: $ 20.

Super Get Info is a much improved version of the Finder Get Info command. Two features make Super Get Info stand out, the ability to view hidden files and change Type and Creator codes. Without resorting to the Terminal you can find and make visible hidden files on your machine or make files invisible to hide them from the casual user. The Type and Creator codes are used less is OS X, but the drag and drop interface of Super Get Info makes it a breeze to change the codes using favorites or finding a document with the correct codes and simply dropping the icon onto Super Get Info's window. It is just as easy to create favorite codes that can be selected from a pop-up menu.

If you ever wondered exactly what files are on your computer, or want a much improved Get Info interface, Super Get Info is the program for you.

ANONYMOUS  The only soft I know that can change permissions when a code 1 error prevents it. Much more efficient than "Maintain" which fails in this case (and in many others too).  
(Version 1.2)

ANONYMOUS  Super Get Info does warn you in the READ ME that you should be careful when changing permissions and that you should fully understand the issues involved. Unfortunately some folks still don't bother to read the manual.  
(Version 1.1)

MACLECTIC  I tried this out when it was a 1.0 product and it was clearly not worth $20 then and I can hardly see how it could be worth it now. However, for those who are too lazy to search out the freeware alternatives, it does the job.

If it were reduced to less than $10, it would be acceptably priced, but now it's for the dumb and rich.  
(Version 1.1)

DANSKINNYMAN  you can easily fix that by repairing permissions on the drive...  
(Version 1.1)

KEVIN S. WILLIS  Be forwarned, it doesn't appear to offer any warnings if you are about to do something stupid! I (stupidly) batch changed the permissions on my system directory and have had to reinstall my system via installing it on another drive and _still_ haven't gotten things back to where they were. Powerful program and useful, but proceed with caution!
