Renaming a text file to a data file is as easy as typing.

A text file is a simple file type that contains plain text in American Standard Code for Information Interchange (ASCII) format. By using ASCII format, the file can be read on any number of operating systems, including Linux, Unix, Macintosh and Windows. Text files can be opened in any number of plain text editors and word processors. Data files are often written in the same language and can also be edited by the same programs. Sometimes, saving a text file as a data file allows for more compatibility when editing between different system types.


Step 1

Launch the program called Notepad by double-clicking on the Notepad icon or by finding it in your list of programs. You can usually find it under the "Accessories" heading.
