Windows Grep is a free tool to search for specific text patterns within a file or a set of files on your system. It also allows you to Search and Replace for text patterns within the file(s). For those from the land of *NIX, this needs no introduction as you can say it is a Windows equivalent of GREP in *NIXes.
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. 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.
Simply, install and launch the tool and provide the text to search, where to search and what files to search and leave it in the safe hands of WinGrep.
