FastFind is a Windows program that provides fast searching for named files. FastFind generates a compact binary index for all files on a system, which it uses to search for filenames, in no more than a few seconds.
If you've ever been frustrated that your hugely powerful PC running Windows takes minutes to find a file with a particular name, then you're not alone, and you'll know why I wrote this program. I was also annoyed that Windows still does not have a simple analog of the Linux 'whereis' facility. (Yes, I've tried the Indexing Service on Windows 2000/XP, and no, it doesn't work.)
