Text Files
Text files are files that we keep our documents and texts or articles in. When we do an English writing assignment which is to be printed off, we would use a text file to store our document in and save it and later print it off. The most common text file is the .doc which is the Microsoft Word document. The next one is .docx which is Microsoft Word Open MXL Document and .txt which is a plain text file.
