that is fine, yhou are at least testing different scenario's.
another easy way is to restore a folder that has no changes in it (example, for me, i hvae yearly invoice folders, year-2015, year-2016, etc)
restore the whole folder, to another location; right click on it, look at properties. look at the SIZE and SIZE on DISK. if the folders are identical, ONE of those numbers should be an exact match to the downloaded folder (one of them, not sure, is some times different, depending on the media it it is stored on, i can never keep them straight)
re: PHDM 16, after initial frustration and many support posts (and subsequent posts by me to the forum, containing support's responses to me), I am getting used to the new interface. It does seem to have all the features of the PHDM 15, just in different spots.

glad the forum could help !
