I noticed that Vuforia creates and frequently modifies some kind of data file in a folder named "QCAR" in the Unity project root folder (e.g. "QCAR/somedata16").
This file is modified every time the application is run in the Unity player.
My question is: Do I need to include this file in version control, or can I ignore it (or even ignore the whole QCAR folder)?
Also, more generally: Are there any other Vuforia-specific files that shouldn't be placed in version control?
