An asterisk (*) can be entered at the beginning or end of a text entry when you want to perform wildcard searches. For example, if you want to find all files with a name that ends with scratch, you could enter *scratch in the Search field. This finds files with names such as vocal.scratch, and dialog2.scratch.A question mark (?) can be used for single-character wildcards. For example, a search on f?ee finds free, and flee. A similar search on f*ee finds frendlee, flippee, flee, free, and so on.
