I recover and transfer a lot of data from various machines that I work on for myself and clients. Sometimes I know what I’m looking for but not where it is – especially when recovering data from failing or failed drives. So when I want to know (and don’t want to wait for the abysmally slow Vista search) I use Everything – a search utility from Voidtools
They list the applications main features as
Small installation file Clean and simple user interface Quick file indexing Quick searching Minimal resource usage Share files with others easily Real-time updating
But for me its the sheer speed of finding what I want across terabytes of storage..
