What does the keyword SEC specify when searching for files?

The keyword SEC, when used in a file search, specifically instructs the search tool to look for "SEC" within file names across all folders. This means that if any file name contains the sequence "SEC," it will be returned in the search results, making it useful for locating files that may be relevant to a particular context, especially if "SEC" is part of a naming convention commonly used by an individual or organization.

The other options do not accurately describe the function of the SEC keyword in this context. For instance, while one might assume that a keyword can denote file types or modification dates, this is not the case here. Each of those attributes typically requires different search criteria or parameters distinct from merely searching for text in file names. The specific nature of the keyword SEC reinforces its utility in narrowing down searches efficiently based on naming conventions.
