Notes about the ROI 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 ROI file type is primarily associated with 'e.Report Designer' by Actuate Corporation. Actuate e.Report Designer Professional is a development environment with which professional developers can create tightly integrated, highly flexible enterprise reports for any Web-enabled application. e.Report Designer Professional lets developers design reports that access any data source, deliver information in any format, and present reports in any conceivable layout, no matter how graphically complex. An instance file is what the user sees when the report is running in the Actuate window.
