dnGrep is a free, open-source Windows desktop utility for searching local folders, files, network paths, and cloud-backed folders. It is aimed at Windows developers and other users who need to search complex file collections rather than only filenames. Search modes include plain text, regular expressions, XPath, fuzzy matching, and byte sequences. The application can search inside Word, Excel, PowerPoint, PDF, OpenDocument, ZIP, 7z, RAR, JAR, and other archive files. It runs on Windows 10, Windows 11, and Windows Server.

Its main strength is the breadth of content and search controls in one desktop application. Whole-file previews with syntax highlighting help inspect results, while search-and-replace for plain-text files includes undo support. File move, copy, and delete actions add workflow tools beyond finding matches. Windows File Explorer right-click integration keeps searches close to file management, and bookmarks plus saved search results support repeatable work. Optional Everything integration can provide indexed file lookup, while integrations with Notepad++, GVim, Visual Studio Code, WinMerge, and Beyond Compare extend its fit for development and comparison workflows.

dnGrep is a focused choice for Windows users who want deep local file and document search without a paid plan. It is particularly suitable when regex, XPath, archive contents, document formats, previews, and replacement matter more than a broad cross-platform experience. The application does not build its own file-content index, so users seeking indexed lookup can pair it with Everything. Its scope centers on files and documents rather than OCR or email-message search. Choose dnGrep for Windows-based development and document-search workflows; choose an alternative when macOS or another operating system, OCR, or email search is central.
