Can I somehow move these files, which constitute the project, back? But how do I know where to put them as I have probably deleted the old folders. I suppose I need to be able to look inside the .sfk file to see where the files are expected to be but opening in Notepad and all I see is mangled text. Am using Vegas Movie Studio HD Platinum 11

These are metadata files and they belong in the same folder as the media that has their name. For example: myvideo.mp4.sfk belongs in the same folder as myvideo.mp4. Having said that, you can simply delete them and they will be recreated as needed when you use the media in a project.
As musicvid pointed out, these are not your project file. That would be the .vf file.
