Masterseeker - jaw-dropping fast file & folder finder
MasterSeeker
I used to use Everything but this has now replaced it because it is so jaw-droppingly fast.
Example - to find all files beginning with 'Cold' took at most 10 seconds across my 11 partitions and thousands upon thousands of files.
Program is only 557k, just unzip it and run from there i.e. it is standalone.
