Windows Grep is a tool for searching files for text strings that you specify. Although Windows and many other programs have file searching capabilities built-in, none can match the power and versatility of Windows Grep.
The program combines the power and flexibility of traditional command line grep utilities available on DOS, UNIX and other platforms with the ease of use of Microsoft Windows.
In addition to searching, Windows Grep also performs global replacing in your files, with complete safety.
Windows Grep is designed for searching plain-ASCII text files, such as program source, HTML, RTF and batch files, but it can also search binary files such as word processor documents, databases, spreadsheets and executables.
