What is the purpose of using a wildcard in a file search?

Correct answer: Find multiple files with similar names or types

The governing concept is pattern-based file searching. A wildcard represents an unknown or variable part of a name, allowing one search pattern to match several files. For example, *.txt can locate files with the .txt extension, while report* can match names beginning with “report.” Therefore option D is correct; wildcards do not restart, resize, or delete files.
