XnView mp folder image Window11 poor quality?

[mapline]

Hi Problem that I have is the poor quality of the folder image in XnView mp vs Win11 explorer, and I feel I must be doing something wrong.
So please help me?

Image of folders in Win11 explorer:

which thumbnail size do you use? And which thumbnail size is used for database?

Hi Thanks for the reply.
Bit confused on thumbnails sizing but had set to default for catalogue to Lossless (zip) with 195 height 144.
Tried Appearance to Custom size width 1000 height 850.
Does that help?

check 'Use case' section in
XnViewMP - thumbnails - understanding quality/size

Hi Pierre
I think I have found the problem. Setting the thumbnails as advised the quality is perfect. The problem occurs when the folder is synced to Google Dive and a green tick is added, then the quality of that folder is reduced. Please find a image showing that when I synced just one folder to Google Drive. Win11 now shows the circled tick separately, as shown in another image, which for explorer solves the issue. I thought in the past the folders were copied from windows but that must not be the case.
Can any change be made.
Many thanks
Michael
