While working with MS-DOS, which command is used to undelete a bunch of files with extension DOC that you have just deleted?
Answer: B
Correct answer: UNDELETE *.DOC
UNDELETE takes a file specification, so UNDELETE *.DOC offers back each deleted file matching that pattern. It works because deletion only marks the directory entry and frees the clusters; the data survives until something else is written over it.
