Files ending in DOCHTML are HTML files created by previous versions of Microsoft Word. Word, Microsoft Corporation's standard text processing, usually stores documents as doc or docx files. To view his documents in a browser, the user can save his document as a DOCHTML file.

This may happen because no default application was associated with this type of files. To associate DOCHTML files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file).
