Recover network rendered .exr from failed job


I really made a mess of things. I accidently launched a bunch of slaves and it brought my server to its knees, so I killed off the processes, but lost access to the job with the master. I can see the .exr files in the slave folders, but if I try to move them into an active slave folder, they aren’t recognized by the master. What can I do to recover these images? When I try to open them in photoshop they appear as black.


Since photoshop can not open them, I guess they were destroyed…

How big are a typical file of them?
