Files with the extension DOTHTML contain templates for Microsoft Word, which were saved as HTML source code. Word, the standard Microsoft Corporation text processing, usually stores templates as a dot or dotx file. To view his documents in a browser, the user can save his document as a DOTHTML file.

DOTHTML is no longer supported by Microsoft. Templates that should be published on the Web should therefore be saved as an mhtml or mht file.
Newer versions of Microsoft Word save HTML code as an html file.

Some programs may be capable only of viewing contents of DOTHTML files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate DOTHTML files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file).
