recover cashed NR?

[PeterSwift]

Our network render Master froze and we lost a lot of pending animations. Not sure what got rendered or not.
Trying to see where the renders can be saved. But I can't fine the most of the latest rendered the last weeks or so, the ID stops at 1600 and we are now on ID 1750.(in the Resource folder (Master folder)
But I can still download som of those to our computers from the network render. So it must be stored somewhere.
How I can find that? I'm trying to search for file names but nothing comes up
Temp folder?
