Sorry - It is on xp - a .FRM (not frn) file - many individual files from a long animation. I accidentally hit cancel when it was highlighted in the network render dialogue window (my machine would often stop mid render because it said it was out of memory but I could always resume the render and it indicated that the precentage of completion was increasing. I can see all the temp files (480 megs worth!) but I don't know how to convert them out or recover within Bryce. Thanks
