dnGrep is a free, open-source Windows search utility that finds text and patterns across files, documents, and compressed archives. It supports plain text, PDFs, Microsoft Office documents, OpenDocument files, and archives such as ZIP, RAR, and 7Z. Users can search using ordinary text, regular expressions, XPath expressions, phonetic queries, or byte sequences. Advanced filters narrow searches by file name, size, date, and other criteria. Results display matching lines and provide full-file previews for easier examination. The application supports search-and-replace operations in text files, including undo functionality. Additional tools include saved search patterns, customizable external editors, and Windows File Explorer context menu integration. It runs on Windows 10, Windows 11, and Windows Server.
