dmmcoy: Thanks for your suggestion. A couple of questions:
a. Re search of textual files: Does Everything allow search by a contained word? For example, say I recall that I used the name "Joe Blow" in a document but don't recall the name of the document; will Everything search the PC and find all files containing the words "Joe Blow", whether in the file name or also within the document itself?
b. Does Everything searches cover email messages, or not? --- I find the Search function in Yahoo Mail to be quite poor.
c. Re photos: Right now, when I get an email with an attached photo I download it; and it gets stored somewhere with a name like <IMG_23456.jpg> that is totally unrememberable. Isn't there a way to rename the file on download, to be say "London 2017"? If I do rename the file, then Everything will find the file if I search for "London", right?
