Everything will search at least some files. Just two days ago I asked it to find a person's name which I knew was in a .docx file and it immediately popped up with the filename, which is really what I wanted. Everything does not actually search your hard drive every time you use it; it searches its database, so searches appear to be nearly instantaneous. It updates its database regularly. It has saved my butt on many occasions. Its primary purpose is to find files but it appears to include text file content in its database. If you search for a unique term or phrase in a file (perhaps a name or a date), it will list every file with that name or date in it. Realistically, you may need several different kinds of search programs, depending on the kinds of tasks you want to perform. In any event, Everything is one of the most indispensable tools I've seen in my 40 yrs. of working with computers.
