Use the original transfer media to copy it to the Vista machine again.. Unfortunately, once the file has been shredded/wiped/written over, you might as well consider it gone.
Hope this helps.
I just ogt a new computer and transferred a fodler to it. After that I used file shredder to shred my free disk space. When it finished I went into the folder and it was empty. So, how can recover this folder. I tried alot of software and nothing has worked.
