SWITCH  FindFilesX is a must-have for AppleScript/Automator developers who need to find lots of files very quickly. We use it in an office setting to find graphic design proofs and compose logo layouts. We search through literally thousands of files and the search results come back in about a second. Spotlight has nothing on this.

So many options to search for: file names, file types, creator code, size, creation/modification dates, label, etc. FindFilesX is versatile, powerful and best of all, it is fast.

Like I said, FindFilesX is for AppleScript/Automator developers. It doesn't have a front end UI because that is not needed for scripting. Marc, if you would have read the product description you would have known what to do with this program. This isn't a Sherlock replacement, it's a tool for serious developers.
