Notepad is a simple text editor included with Microsoft Windows.
It is one of the most common text-only editors. The resulting files - typically saved with the .txt extension - have no format tags or styles, making the program suitable for editing system files that are to be used in an MS-DOS environment. Notepad can edit files of almost any format.
Early versions of Notepad offered only the most basic functions, such as finding text. Newer versions of Windows include an updated version of Notepad with a search and replace function, as well as [Ctrl-X] and similar keyboard shortcuts. In older versions such as those included with Windows 95, 98, ME and 3.1, there is a fixed limit on the size of the file being edited.
