What is a DOC file?
DOC is a proprietary document format developed by Microsoft for its Word processing software. It was the default format for Microsoft Word documents from the early 1990s until 2007.
DOC files can contain rich text, images, tables, styles, macros, and more. While it has largely been replaced by DOCX, the format is still widely used due to its broad compatibility and long-standing history.
How to open DOC files
DOC files can be opened with Microsoft Word, LibreOffice Writer, Google Docs, and many other word processors. They remain compatible across many systems due to their long-standing use.
You can convert DOC files to DOCX, PDF, or ODT using AnyConv or built-in export functions in editing tools.
