RUFTY TUFTY  "The Unarchiver" should be able to do most of what you need, but if you really need Stuffit Expander, here's a link to the current direct download (no email address required).

RUFTY TUFTY  EasyFind does NOT use an index. That's clearly stated in the first sentence of the description.

The reason it's so useful (when Spotlight isn't) is that Spotlight only indexes part of your system, and doesn't find anything in the areas that aren't indexed. And, indexing >everything< would take a long time, and take a lot of space for the index.

The genius of EasyFind is that it is fairly fast, considering that it doesn't use an index. I use it a few times a month to find system files, etc., and a couple of minutes or so is no big deal (I do something else while I'm waiting). 3 or 4 minutes to search an entire server over the network is actually pretty impressive.

While it's not as fast as you might like, you might want to ask - what's the alternative? The only way to do it faster is to build an index, with all the overhead that entails.

RUFTY TUFTY  I agree with the negative reviews below. This was a decent product, and would be if the developer would maintain it and fix the bugs.

However, I've had the same crash bug since I paid for it a year ago, have contacted the developer several times, and he's shown no real interest in fixing it. Apparently there are other unfixed bugs (no update since the initial 4.0 release).

At this point, I've stop using iClip, consider the $29 a loss, and would never buy another product from this developer.
