backing up xnview

[Ilikemyprivacy]

If I wanted to backup important custom data in xnview what file do I need to make a copy of? I will explain what data I mean.

I'm using xnview to organize collections of photos into groups so that I can bring up groups of photos without having to go through my overall collection and hand pick the ones I want every time. My images are organized into folders based on like image sets but I may only want to look at a couple of images per set. I experimented with making a slideshow (that saves easily into files) but I instead took a greater interest in the assigning of tags within those folders, then I can filter out by tags. I also made some custom changes to what my mouse buttons do. I also liked being able to save sessions where I pull up images in tabs but it looks like I can only save one session at a time. So where does all this data get stored if I want to make a backup?

you have all files used in 'Settings>Paths>open config file location'

I see it, I also see 7 files. Is it just the "xnview" type "configuration settings" file that I need?

Oh I see, you said "all files" OK, I get it. Thank you
