Search Text in Various Types of Text Files

Much of the information on your computer is stored in text files. This is a general term for a large number of file types with different extensions, but they have in common that the text is stored in the most simple form – as a series of symbols.


The most common types of text files are as follows.


Text files with the extension “.txt” contain unformatted text. Such files are recognized by all the text editors and word processors.


html & htm
Files with “.html” and “.htm” extensions are used to format and display both text and images in Web browsers. They contain markup code, which is stored in plain text format. Users do not usually see the HTML source code, but if  they want to, they may go to the View menu of the Web browser and select View Source. The “.htm” extension is less frequently used in comparison with the “.html” extension.


cpp & h
C++ is among the most frequently used programming languages. Code files have a “.cpp” extension and header files, also called include files, usually have a “.h” extension. Files with a “.cpp” extension can be opened with text editors, but they are usually edited with programs, providing syntax highlighting, auto completion, etc., and header files hold declarations for other files.


Java is another very popular programming language. It is intended for developers of applications in such a way that allows code, running on one platform, to run on another one without being recompiled. Much of the syntaxt in Java is derived from C and C++.


PHP, an abbreviation which stands for Hypertext Preprocessor, is an open source scripting language. The default extension for such files is “.php” and they can contain HTML, text, PHP code and JavaScript code. PHP can do quite a lot of things: read, write, open and close files on the server, delete, add and modify data in the database, etc.



JSP stands for JavaServer Pages. It is a technology that enables developers of software to create dynamic web content. It uses the Java programming language and resembles PHP. The file extension is “.jsp”.



XML stands for Extensible Markup Language. It is a markup language, defining rules that can be read both by people and by machines. Files with a “.xml” extension can store data and transfer it both over the Internet and between programs.
