Tried both but I found that changing "customize" in properties is a real hassle to change all the folders that contains video files, and not seeing thumbnails is inconvenient as there are lots of pictures without meaningful file names that my camera created.
I save video files from Courera online courses for later viewing, and the file names has meaningful descriptions so I don't need thumbnails for videos, but for pictures, I want to have thumbnails view. Unfortunately, the file explorer's option is either turn on or off thumbnails view for both pictures and videos.
One solution I found and settled on is:
- Turn off thumbnails view in folder's view options.
- Use 3rd party software, SageThumbs (https://code.google.com/p/sagethumbs/)
I hope this post is helpful for anyone experiencing the same issue and having the same needs.
