If you are like me you probably love to download various stuff from the internet and then over time when you have a lot of files in the downloads folder it is slow to load, or when you want to sort by date for example it takes forever or never finishes.

What happens here is is downloads folder is optimized as pictures folder so probably windows is trying to generate a thumbnail of the files/picture.

Here is the solution:

1. Right click on the downloads folder in windows explorer
2. You need to go to Customize tab > Select General Items and apply this to all the subfolders as well
   Now you downloads folder will load just fine :-)
