I did some investigation on this and it looks like it is an empty file that is generated sometimes in Unity Playmode. I wouldn't worry about it.

However, I would like to mention that Unity 2017.1 is not a supported version of Vuforia 6.2.10 and it is recommended you use Unity 5.6 instead. You may run into other unknown issues while using 2017.1.

Thanks,

-Vuforia Support

Vuforia 6.2.10 + Unity 2017.1.0f3

File location is <project_root>/QCAR/somedata16 (where <project_root> is the root folder of Unity project).

File appears after I run a scene with Vuforia content (AR camera and image marker) in it.

What version of Vuforia are you using? I'm not seeing this file in Vuforia 6.2.10.

Thanks,

-Vuforia Support?

Wondering as well. Does it have to be under version control?

What is the mysterious somedata16?
