A text editor is a type of program used for editing plain text files. Text editors are provided with operating systems and software development packages, and can be used to change configuration files, documentation files and programming language source code. Sometimes it is used to remove the formatting of a chunk of text that copied from a web page or other rich text editors. In Windows operating system, Notepad program is a text editor. Text editor is familiar with every programmer; it is a very important part of any IDE (Integrated Development Environment). In IDE, it is used to write source code.
My Text Editor (MTE) is a common text-only (plain text) editor. The resulting files—typically saved with the .txt extension—have no format tags or styles, making the program suitable for editing system files and, and occasionally, source code for later compilation or execution. It is also useful for its negligible use of system resources; making for quick load time and processing time, especially on under-powered hardware. For simplification, MTE is a single document interface (SDI) with a menu and a large text area to typing. It allows user to save the content in ASCII or Unicode code with maximum 16Kb in size.
