Open FACES File
FACES files were originally developed by Oracle Corporation for the JavaServer Faces software application.
Such software for JavaServer FACES is used in the gallery of Samsung mobile devices.
The FACES filename extension is associated with image files captured by Samsung mobile phone facial recognition software, based on JavaServer FACES.
These FACES files contain cropped photos of the faces of the subjects (people, dogs, etc.) in the images stored in the phone gallery.
Some UNIX-based operating systems such as Ubuntu save each user's avatar in a PNG or bitmap file with the FACES file name extension.
These types of FACES files are used by the GNOME Display Manager when displaying a user's profile on the login or settings screen.
You can also open a FACES file with XnView image processing software.
Some smart watches store watch faces in FACES files.
FACES files should not be attempted to be opened by software other than those listed above.
