Previous versions of files burned on DVD-R
I hope this will fit into the troubleshooting section of the Forum.
I'm writing a long text and keeping it divided in chapters, i.e. I have created a different Word file for each chapter. I keep a copy of the whole folder on my laptop and back it up on a Kingston memory stick and on a DVD-R.
I had a shock yesterday when I found out that one of my chapters was a 0kb file and it was in fact a blank Word page. I have no idea how this happened.
I went to check my back-ups and both the Kingston memory stick and the DVD-R show the same 0kb version of the file.
I've recently changed laptop and the files I have on it were copied from the memory stick so I think there is no point in trying to find an older version of the 'empty file' on the laptop's hard drive.
I think my only hope might be the DVD-R.
And this is when you will see that, unfortunately, I am not at all an expert, so I can only describe what I was doing.
To put my files on the DVD-R I was simply dragging and dropping them in Windows 7 and then use the basic command 'Burn to disc'; I don't think I ever closed or finalised the disc as I was able to keep writing and copying files on it. The software would ask me if I wanted to replace files with the same name and I would say yes.
So, now I have a DVD-R that has the latest version of my folder with the 0kb file. However, whilst the folder on my laptop is 55Mb in size, the DVD-R, that allegedly contains the same folder, says I have used 818Mb of it.
The DVD is a DVD-R, not DVD-RW. Does this mean that the previous versions of my 'empty file' are still there in the layers of the DVD-R somewhere? If so, how do I retrieve them? Or can you actually erase a file from a DVD-R by copying one with the same name on it? If so, what are the 818Mb burned on my disc?
I'd be extremely grateful for any help, advice and explanation. I am slightly desperate to retrieve my file if there is any chance. I am now using Windows 10, btw, and I have tried the most basic things, like looking for previous versions of files etc, but I don't get any joy. My only hope lies in those 818MB...
Thank you very much for reading.
