Perhaps it forgot to preserve that first byte in the file. Which is horrible, but then there's the "Conflict" error. All I can make of this is that the server is probably rejecting the MOVE request for some reason. That might be reasonable if the destination file already existed, but I don't think it does in this case, so who knows. Only thing I'm sure of is, I never want to entrust this particular webdav server with any of my data! """]]
