Which utility native to Windows can perform string searches across multiple directories?

The utility native to Windows that can perform string searches across multiple directories is STRINGS. This tool is specifically designed to scan binary files and display the sequences of printable characters it finds, making it particularly useful for recovering text data from executables and other non-text files. STRINGS can traverse directories and apply filters to limit results, allowing investigators to effectively search for specific strings or patterns within a wide array of files.

On the other hand, GREP is primarily a Unix/Linux command-line utility that performs similar functions but is not a native Windows tool. DD is a command-line utility used primarily for copying and converting files, particularly in low-level operations, while LIST does not refer to a specific utility in this context. Thus, STRINGS stands out as the appropriate choice for string searching in the Windows environment.
