What is a DOT file?

A DOT file is a template created by Microsoft Word, a word processing application and may be opened by various word processors. It contains pre-formatted document settings, such as headers, footers, margins, font sizes, and other common page styles. DOT files are used to create multiple documents that have similar formatting, such as company letterheads, business memos, or envelopes.

Some templates are included with Microsoft Word that allow you to create a document such as a resume, cover letter, newsletter, or business plan, with the formatting already in place. You can also create your own templates with custom page layout, fonts, and styles.

DOT files were replaced by .DOTX files with the release of Microsoft Office 2007. DOTX files are saved in the newer Open XML-based Word document format and can be opened in Microsoft Word 2007 or previous versions of Word with Open XML component support.

Common DOT Filenames

Normal.dot - Default template used for creating new documents in Microsoft Word. It is the template that is opened when users open Word.

How do I open a DOT file?

You can open DOT files with Microsoft Word in Windows and macOS. The word processor is also available for Android and iOS devices, but only the iOS version supports DOT files.

Other word processors can also open DOT files but they may not fully support the formatting of the original templates. Some examples include Apache OpenOffice Writer (multiplatform), Kingsoft Writer (multiplatform), and Apple Pages (Mac). If you are a Mac user simply looking to view a DOT file, you can use Apple Preview, which comes bundled with macOS.

You can also upload DOT files to Google Docs, which is a free web and mobile (Android and iOS) application that allows you to view, edit, save, and convert the document.
