The program is called Everything.

I use it a lot to find a file that I know part of the name.

For example, I have a picture of my old truck.  It may be 76truck.jpg  but putting truck is often enough to show me a bunch of files with truck in the name.  I could say ?truck?,jpg and have even better luck because on jpg files would show up.

Also this program is fast, call it instant.  You can sort the results by date,size name, type.

I've used it for years and it's never caused a problem, no ads.
