Hi Dave
Windows settings for the recycle bin are only good for older machines. The default setting is 10% which if you have a newer system with a large hard drive that is a lot of space. I have always set mine to 1% that is still a good amount of space for the amount of times you actually use it.
If you don't know how to do that, just right click on the recycle icon and select properties you will see a slider and you can set it anywhere you like.
