The purpose and contents of an x1i file cannot be identified from the extension alone.

No vendor, application, or established file format is currently associated with the x1i file extension. Its intended purpose and internal contents are therefore unknown.
The format's platform availability and current status cannot be determined without identifying the software or device that created the x1i file.
No specific program is known to open an x1i file. The file should be identified through the application, device, or source from which it was obtained before an opening program is selected.
An x1i file cannot be reliably converted while its format and creating software are unknown. Conversion requires identifying the file's format first.
