Confirmed fixed. Many thanks.

Confirmed fixed. Thank you.

Fixed. Many thanks.

> yes XnViewMP folder is created but no .ini or .db

However, I didn't mention in the last step that I was switching to Dark theme in the Startup Wizard - that is the crucial difference.

Without Dark theme = no ...

I don't know how to simplify that English.

but it only happens with `Create thumbnails for whole folder` unchecked - so performance / behaviour is degraded as a result of that setting

OK, more detail:

I have C: and D: drives. D: for data and downloads, C: for Windows, programs and User data

1. I download https://www.xnview.com/download.php?file=XnViewMP-win-x64.zip to "D:\Downloads"
2. I extract zip to "D:\Downloads\XnViewMP"
3. I have removed "C:\Users\USER\AppData\Roaming ...

I just tried it again. Same issue.

> you should have an old xnview.ini

2. change function to 'thumbnails per column' and adjust so they are very large (e.g. 5 thumbnails per column)
3. warning pops up `Sized of cached thumbnails is smaller than chosen one.`

1. start portable edition
2. select 'Portable' for settings location
3. `C:\Users\USER\AppData\Roaming\XnViewMP` is created with Thumb.db, XnView.db, xnview.ini
4. close XnView
5. reopen (it has forgotten that I chose Dark theme so I change it), Settings > Paths > Configuration = Portable
6. close ...
