Notes about the HCA 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 HCA file type is primarily associated with 'Hammer Call Analyzer' by Empirix Inc.. The Hammer Call Analyzer (HCA) is an application-aware analysis tool that uses a passive IP and TDM capture engine to monitor and capture network traffic.
