Windows 7 Explorer scanning folder when opening the folder

Your folder is "customized" to display images, movies, etc, so Windows keeps scanning the folder every time you open it to give you thumbnails, etc.

To stop Windows from re-scanning the folder each time:

• Right click the folder, select properties.
• Select the "Customize" tab
• There is a drop down labelled "optimize this folder for". Select "Documents" form the drop down.

This usually happens on the first load of the view or a refresh. Explorer has to content with preview filters, new icons, etc etc etc. But after the first load, you are golden. I have some similar folders.

If you'd like to know more about how Explorer's process, I'd hit up MSDN. Especially concentrate on the interfaces.
