Download AstroGrep – Fast File Text Search Utility for Windows

AstroGrep is a free, open-source Windows utility for searching text within files across folders and directory trees. It provides a graphical interface for performing grep-style searches, making the power of regular expression file searching accessible to users who prefer a point-and-click workflow over command-line tools.

The application delivers fast search results with syntax-highlighted previews of matching lines directly in the results panel. It supports plain text searches, wildcard patterns, and full regular expression matching, with options to filter by file type, date modified, file size, and whether to search recursively through subdirectories.

AstroGrep is portable, lightweight, and requires no installation. It is a practical everyday tool for developers, writers, and system administrators who frequently need to locate specific strings or patterns across large collections of source files, log files, configuration files, or documents.
