Adobe PDF files—short for portable document format files—are one of the most commonly used file types today. If you've ever downloaded a printable form or document from the Web, such as an IRS tax form, there's a good chance it was a PDF file. Whenever you see a file that ends with .pdf, that means it's a PDF file.

Microsoft Word started using the DOC format and file extension over 30 years ago in the very first release of Word for MS-DOS. As an extension explicitly for Microsoft’s proprietary document processor, the format was also proprietary: Word was the only program that officially supported DOC files until Microsoft opened the specification in 2006, after which it was reverse-engineered.
Under pressure from the rising competition of the free and open-source Open Office and its competing Open Document Format (ODF), Microsoft pushed for the adoption of an even broader open standard in the early 2000s. This culminated in the development of the DOCX file format, along with its companions like XLSX for spreadsheets and PPTX for presentations.
