In the search box of File Explorer, which search pattern finds all Word documents in the current folder whose names start with “Unit”?
Unit*.docx
In file searches the asterisk (*) is a wildcard that stands for any number of characters, so placing it after a fixed word matches every name beginning with that word.
To find Word documents whose names start with “Unit”, the fixed part “Unit” is followed by * to allow any remaining characters, and the extension .docx restricts the results to Word files, giving the pattern Unit*.docx.
“Unit?.txt” uses ? (a single character) and the wrong .txt extension, “*Unit.docx” matches names ending in “Unit”, and “Unit* .docx” contains a stray space that breaks the pattern.
Hence, the correct search pattern is Unit*.docx.
