I have over 12000 .jpg photos in sub-folders in the Windows My Pictures folder. A couple of years ago I was pointed to the registry key << HKEY_CURRENT_USER\Control Panel\Screen Saver.Slideshow>> and reset MaxSuccessfulFiles REG_DWORD to 20000 in order to access them all. My wife and I stop several times a day and test our memories as a different photo pops up.
I turned on Show File Names in the Settings screen of this screen saver in Display Properties/Screen Saver/My Pictures Slideshow (DisplayFileNames REG_DWORD = 1). Unfortunately, the complete path is shown with the photo filename at the end. If the path is longer than the width of the photo, often the parent folder is replaced with three dots. I would like only the parent folder plus the filename displayed so I could easily locate a photo I saw on the screen. Is there a registry entry or some other was to do this?
