why is good?
yes, I see the folders
anyway, I have change it to E:\- Temp\Pics\XnViewMP\ and reloaded the thumbnail but nothing is changed
edit
I think I understood what the problem is, I moved the thumbnail size led while in Settings-Catalog the old size was still set.
I didn't understand why the path changed for its own while in xnview.ini it was set correctly, but anyway the problem is solved... thanks

I thought the problem was completely solved but it is not. If I open a folder with many photos, the scan occurs and the thumbnails are created, then if I change folder and then go back to the previous one, a "mini scan" occurs that I do not understand. It is brief but it does not seem normal to me that it is there.
