What is a .dotm file?
File extension details and usage information
A DOTM file is a template file created by Microsoft Word, the widely used word processing software. It is part of the Office Open XML (OOXML) standard introduced with Microsoft Office 2007. The 'm' in the extension stands for 'macros,' indicating that the file can store VBA (Visual Basic for Applications) macros. These templates are used to create multiple documents with the same layout, styles, and automated scripts. Unlike standard DOCX files, DOTM files are designed to be a starting point for new documents; when opened, Word creates a new, unsaved document based on the template's settings. This format is essential for corporate environments where standardized branding, automated form filling, or complex document generation is required. Because they can contain executable code in the form of macros, they carry a higher security risk than standard templates (DOTX) and are often scrutinized by email filters and antivirus software to prevent the spread of malicious scripts. They are essentially ZIP-compressed archives containing XML files that define the document structure, formatting, and the binary macro data.

- Check whether the application supports exporting to common formats.
- Be careful with online converters when working with private, business, or sensitive files.

File safety tips
Use caution with unknown files
Only open files from trusted sources. Before opening a .dotm file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
