Notes about the HMSKIN file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The HMSKIN file type is primarily associated with 'Help & Manual' by EC Software GmbH. Help & Manual is a single-source help authoring and content management system for both single and multi-author editing. Working with Help & Manual is as easy as writing text with a word processor, while all content is saved as pure XML in the background.
