update thumbnail / preview in W10

Post by Tony_Bullet »

Good morning,
When I crop an image with XNView and save it, the preview that I then see in Windows Explorer matches my original image, not the one I cropped. So how do we make Explorer take into account the new image, the one that’s cropped?
I don’t know if this is a setting in XNView (I tried several options in thumbnail and catalog) or in Windows.
Thank you for your help.
Tony.

Hi,
I think the issue you are experiencing may be due to Windows Explorer's thumbnail cache not being updated after you crop an image in XnView. Here are some steps you can take to update the thumbnail cache in Windows Explorer:

1. Clear thumbnail cache: Clearing the thumbnail cache in Windows can often resolve thumbnail display issues. To do this, open File Explorer, go to the View tab, and select "Options". In the Folder Options window, go to the View tab and click the "Clear" button next to "Clear File Explorer history". This will clear the thumbnail cache.

2. Rebuild thumbnail cache: If clearing the cache does not resolve the issue, you may need to rebuild the thumbnail cache. You can do this by opening Command Prompt as an administrator and running the following command:

Code: Select all

taskkill /f /im explorer.exe
cd /d %userprofile%\AppData\Local
del IconCache.db /a
start explorer.exe
This will kill the explorer process, delete the IconCache.db file, and restart explorer.

3. Change thumbnail view settings: If the issue persists, you can try changing the thumbnail view settings in Windows Explorer. Go to the View tab and select "Options". In the Folder Options window, go to the View tab and make sure that the "Always show icons, never thumbnails" option is unchecked. You may also want to try changing the size of the thumbnails to see if this affects the display.

4. Check XnView settings: Make sure that XnView is set to save cropped images in the correct format and with the correct file extension. Go to the Tools menu and select "Options". In the General tab, make sure that the "Save format" option is set to the correct format (e.g. JPEG, PNG) and that the "Add extension to file name" option is checked.

Thank you very much for your answer, Remedio! It seems very accurate.
However in the mean time, I reinstalled Windows (for other reasons) and this problem did not show again after I did it.
Nevertheless, I am sure this answer could be very useful to someone else in the future.
Have a nice day.
Tony.
