What action closes a folder and access to its documents inside?

• A. Expand a folder
• B. Collapse a folder
• C. File Extension
• D. Pixel

Answer: (B)

Collapsing a folder hides its contents, effectively closing access to the documents inside. In most file managers, you can expand a folder to reveal what’s inside; collapsing does the opposite, reducing the folder to a single line or icon and concealing the inner files until you expand again. Expanding would open or reveal the documents, which is the opposite of closing them. The other terms aren’t related to visibility of folder contents: a file extension describes the type of a file, and a pixel relates to display resolution or image detail, not how folders are shown or hidden.
