Looks like this software may be abandoned. The links to the program no longer work but the developer is still accessible @ http://www.synthesisstudios.com/studios/filespot. Too bad, it is a good piece of software. Of course, it is quite possible that the new features in Snow Leopard will make programs like this redundant.I contacted the developer and this was their response:

It is on hold for the time being, but within a month or two we will be deciding whether to continue development or not.

This thing has potential. It's clean, logical, and will help me get a handle on all the stuff I've got on my computer.

That said, it's buggy. I have crashed the app twice in the first ten minutes of use. Last crash happened when I was entering a search term when creating a new saved search.

Considering the app's heritage, I believe the developers will get this thing straightened out soon. Hope so. Until then, I'll hang onto my $20.

Everybody seems to like MoRU here, a lot, yet some give it less than 5 stars. Maybe I'm overeager in my feelings about MoRU, but I'd give it 10 stars if I could. It fulfills what I have wanted for so long; Spotlight came close but its results were difficult to sort through and find that ONE file that you REALLY wanted.

With MoRU, the results seem to give me EXACTLY what I am looking for, every time, at least so far. You can choose what criteria to use in searching, if you need to narrow it any, AND, perhaps most importantly, you can choose WHERE to search. Plus, it has additional capabilities in keeping all your most-used applications and docs handy, also your most recently modified files.

Insanely great, I say! Download it, try it, send in your payment, a pittance for such a wonderful app.

Just like everyone else says, its powerful, fast and way better than spotlight which never gives you enough information with it's pretty but useless interface.

Moru suffers from one big problem (unless I am missing something) it is an application that you launch and sits in the dock. Its functionality goes beyond spotlight, but it is not integrated into the OS as a spotlight replacement so every-time you want to do a search you have to launch the darn thing (a total pain in evaluation mode as it sits there with a nag screen for several seconds) before you can search. There is no system wide hot key, aand there is nothing in the preferences that will put it in the login items (not hard to do manually, but it should be a preference). And then there are the saved smart searches (like smart folders). I don't want every search I do to be saved and listed like a folder in mail, I just want to search.

I have found a better (for me) alternative in the form of Command-F Find. It allows you to search with several criteria, it shows file paths, is as fast (or not) as spotlight and its built into the OS.

absolutely amazing. This should really be intergrated into the Finder. Fast, powerful and cheap. Well worth checking out. One wish, I'd love to see thumbnail previews!
