Show/unshow hidden in the folder options doesn't do anything.
If I click the file properties and click 'hide' they only hide if I have the folders set to 'not show hidden files'. However, the folder.jpg artwork for the other older folders, stays hidden regardless if set to hide/unhide.
Only way to see the other files, is to show hidden protected windows files.
Must be a way to do it, last summer it did it on it's own, though I think I was still using WinXP, now I have Win7x64.
