With "SearchInFiles" you can search a text string within a file showing the line number of the file where is located.
The most useful function is the possibility to search across multiple files, folders or sub-folders showing the file and the line in which the searched string is located.
It works with all simple text files, such as txt, rtf, html files, css, xml, c, m, java.
