Everything is insanely fast. Even though I have X1 Search and use that for content search (I commented on GP about that), I still use Everything for any search on filenames or directories because it opens instantly. I also love that typing slashes at the beginning or end of a phrase filters a search to a directory. It even supports Regex.
Oh yeah for sure, I found everything pretty quickly and it's definitely indispensable. I'd love if it did content search, but file search is great and fast and straightforward.
