I had a terrible thing happen to Win 10 that resulted in me deleting my favor Music Folder. I was able to recover all music using Recuva. However, once all songs were restored the program added an extra extension to each file.
For example: VLC media file (. mp3) (. mp3). This double extension has been added to all my music and now I can't play any of them and I don't know how to correct the double extension.
