Is there a way to increase how much is cached for thumbnail views of pictures?

If I'm looking through a folder of .png files for example, with "medium" set as the view size, the screen will eventually fill all the thumbnails with the appropriate pictures. But as I scroll down it takes a while for the pictures to fill in again.

I would like a way for "off screen" pictures to fill in before I get the that section of the screen. Is there a way to do this?

Solution 1:

The pictures will only take time the first time they are cached for thumbnail.
The cache increases as more pictures are loaded.

You cannot set the size for the cache.

You can see the currently occupied cache by selecting Disk Cleanup... for C drive. (or the drive where you have installed Windows)

After about 7000 images have been cached Windows 7 stops caching new images.
You can solve this by deleting the thumbnail cache using Disk Cleanup...

If your problem is that thumbnail cache is randomly being deleted and recreated then take a look at
