Notes about the ZUML file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The ZUML file type is primarily associated with 'Poseidon for UML' by Gentleware AG. Poseidon for UML is a professional UML CASE tool with roots in the open source project ArgoUML. ZUML files are ZIP files containing a .PROJ file with project information, and an .XMI file with the model and layout information; in accordance with the Diagram Interchange standard.
