Understanding Defense+ and Pending Files

Ok I don’t quite understand how Defense+ Pending Files works so please bear with me.

  1. I am assuming files that are listed in the Pending Files list are files that are new or have been modified that aren’t in the Comodo safe or “my own” safe list, is that correct?

  2. How does this work. ie. say I install a new unknown program that is not on any safe lists, does defense+ move or list? unknown files into the pending files list? What I am worried about is if it is moving them would this screw up say the installation of the program?

Looking at the list now it has listed (or moved) all of these files in the Shadow Copy area of Windows, does that mean that my “Shadow Copy” of those files is not there and that they are in a holding area within the Comodo area?
