What is an SFERA file?
A SFERA file is a photo created by AMA Photo 360° by Sfera, a photo and sound capture application. It contains a 360° panorama photo and recorded audio. SFERA files can be shared on Facebook or through messages and email.
The SFERA file can be created only using Photo 360° by Sfera for Android. However, you can open SFERA files in Windows using the Sfera Viewer program. To do so, open Sfera Viewer, select File → Open, navigate to your file, and click Open.
NOTE: Sfera Viewer has been discontinued.
