Help & Manual is documentation software from EC Software GmbH. An hmx file stores a Help & Manual help project, including its documentation content and project settings.

MixlleniumEngine web server module template

File type category:
Various data file

Date updated: October 11, 2026

Record marked as obsolete and not updated for a long time.

MixlleniumEngine (Haydee) uses the hmx file as a web server module template for its Apache-based solution.

The hmx file contains template data used by the MixlleniumEngine web server module.

MixlleniumEngine and this format are obsolete, so current web-server software may not support the file.
