Listary 3

Listary 3 solves the age-old problem of forgetting where you have stored files. It’s always running and you simply bring it up and search for the file you need. Because it incorporates auto complete and wildcard features, it often locates files within seconds.

Listary searches in Windows Explorer and also the Open and Save functions. It’s a free Windows-based app. but there’s also a pro version for $19.95.
