Notepad was ""born"" by Microsoft before Windows. At the time, Notepad was integrated as a packaged application for Microsoft Mouse in 1983, running in an MS-DOS environment.
By 1985, Notepad was developed by Microsoft and integrated into the first 1.0 release of Windows. And since then Notepad has become ""inseparable"" from the Windows platform.

The golden age of Notepad is associated with the history of the legendary Windows XP - the most popular and used operating system version.
By the later high-end versions such as Windows 7, 8, 10, 13, people had a lot of text editing software to replace Notepad, such as Notepad ++. However, that does not affect Notepad much as it is still one of the programs required in Windows.
The text is written in Notepad when saved as a file with the extension .txt. This is the ""plain text"" Plain text file format - no formatting tags or any other type of format. The file.txt can be imported, read, edited by many tools. In particular, this format will make the .txt file occupy a small space compared to the original document file: a novel with 100,000 pages can be saved as a .txt file of only half a megabyte.

In the early versions, Notepad included only some basic functions, such as searching for text. Newer versions of Windows include upgraded Notepad with more advanced search and replace functions, such as Ctrl + F for searching. In older versions of Notepad (included with Windows 95, 98, ME, 3.1) the maximum size of a Notepad-edited file is limited to 64-kilobytes, which is the OS's EDIT class limit. .
Up to Windows 95, the only font type that Notepad uses is Fixedsys. Windows NT 4.0 and 98 changed this typeface. Windows 2000 takes the default typeface as Lucida Console.
In Windows NT-based versions of Windows, Notepad can edit traditional 8-bit text files, Unicode text files (both UTF-8 and UTF-16, with UTF-16 included with ""little- endian ""and"" big-endian "")."
