Crash while recording DVD

Good evening folks.
I was just recording an DVD with me Nero 7 when my computer crashed. It was a total of approximateli 4GB of space to convert and burn that now are " missing" of my total HD space... I tried a lot of options but could not find it.
Can someone help me please.
Thank you.

 

You could try looking here to see where the files are located

 

Thank you so much Gwendolin, but it seems it´s not working... I´m using the version 7, so the Nero vision Its a little bit different. I found a couple of temp files but I´m still missing my 4Gb.
Thank you one more time.

 

I am also using Nero 7 so it should be the same...the app of Nero is Nero Vision.
