hi
it seems XnView is creating recursive folders.
also it takes forever to load.
here is a screenshot from "WinDir portable":

you see how "File1.dat" has "XnView" inside it which has another "File1.dat" inside which has another "XnView" inside it ? is that normal?
I have just tried, nothing similar happens on my side.
I dont know what is the file in your case containing, something very big, it starts with something 2.3Gb.
I would try to see what it is looking like when it is closed, means not running.
Try to remove this file1.dat , copy it somewhere else, and see if now all works.
On my side, xnview opens in less then a second.
Otherweise go and reinstall.
