Desktop Background Slideshow is a neat little feature in Windows 7 which helps you shuffle your desktop background from a image file store folder, at predefined intervals. But, as Windows doesn’t show the file name of the currently displayed wallpaper, it becomes a problem if you have thousands of images in a store folder and you need to find the file name and the directory location of the currently displayed wallpaper.
Here is a small script which adds the Desktop Background File Location option in the Desktop context menu, which opens the current wallpaper file’s target folder and selects the file.
1. Download WPTargetDir.zip, unzip and extract the contents to a folder.
2. Move the file WPTargetDir.vbs to the Windows directory.
3. Double-click Add.reg to add the context menu option.
4. Hold the SHIFT key down and right-click on an empty area in the Desktop. You’ll see the Desktop Background File Location option.

To remove/uninstall this option, run the file undo.reg, and then manually delete WPTargetDir.vbs manually from the Windows folder.
