The Missing File Names

When I opened my wallpapers folder today,all my file names where missing in it.First i thought it was an virus and was going for a reformat but i noticed that the filenames where missing only in that folder and other ones where fine.

Then i came to know that it was nothing more than a windows trick.If one presses shift and enters a folder,the filename settings changes in the folder i.e the filenames disappear and it is reverted back by just doing the same.Check these snap shots out..
