Notes about the IOM 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 IOM file type is primarily associated with 'Omniscope' by Visokio. These files are a standalone package of data, media and configuration information. When opened in the free Viewer you can use Omniscope interactive data navigation and visualisation for that data and media. A version of Omniscope .IOK files, these files will not open in the free Omniscope Viewer but only in activated editions of Visokio applications. (Also see .IOK files.)
