Your Sources folder seems to be truncated; mine has 215 items while yours has only 84 items.
By truncated, I don't mean that I can't see everything in it . . . mine has been cut off at the bottom, but still shows the number of items in the folder. I have install.esd highlighted so you can see it, and also, you should see how many items beginning with "i" are there too.
Right click Start>Control Panel>File Explorer Options: See screenshot below to be sure you actually have "show hidden folders" active.
Hope this will help you find it.
