.HAY File

The hay file extension was used in the past for Haydee web server modules from  MixlleniumEngine. Looks like some kind of XML, but as the software seems no longer available, it is probably obsolete by now.

This hay file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

Probably can be edited with text editor.

How to convert:

Probably cannot be converted to anything else.
