What you can do is pick the files from the original location and put them at your desktop. To find the location of a file, right click on the thumbnail of the file and select properties. Now, at the bottom of the Properties dialog, you will find the location of the image file. You can go to the location directly by clicking on the folder icon there. Now you can move this image yourself to the desktop.
Once you have done that, you will need to reconnect it to the thumbnail in your PASE which you can do by File>Reconnect. Do it manually if u want to do it fast and automatically otherwise.
